schrodinger.application.phase.shape_screen_reporter.tasks module

class schrodinger.application.phase.shape_screen_reporter.tasks.CreateScreeningDBTask(*args, _param_type=<object object>, **kwargs)

Bases: schrodinger.application.phase.shape_screen_reporter.tasks._AbstractShapeScreenReporterTaskMixin, schrodinger.tasks.jobtasks.CmdJobTask

Task to create a virtual screening database. Adds a label property to the newly created DB in a postprocessor.

MODE = 'create'
class Input(*args, _param_type=<object object>, **kwargs)

Bases: schrodinger.models.parameters.CompoundParam

hits_file: schrodinger.tasks.tasks.TaskFile

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

When a Param value is set, the valueChanged signal is emitted. Params can be serialized and deserialized to and from JSON. Params can also be nested:

class Atom(CompoundParam):
    coord: Coord
    element: str
query_file: schrodinger.tasks.tasks.TaskFile

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

When a Param value is set, the valueChanged signal is emitted. Params can be serialized and deserialized to and from JSON. Params can also be nested:

class Atom(CompoundParam):
    coord: Coord
    element: str
props: List[str]

A Param to represent lists. Values of this param will have a mutated signal that will be emitted whenever any mutation method is called.

The constructor optionally takes a item_class keyword argument to specify what type of class the items in the list will be. This information will be used for jsonifying the list if specified.

__init__(*args, **kwargs)
addFuncToGroup(func, group=None, order=None)

Adds a function to the specified chain. Typically used for adding functions that are not methods of this object.

The function may optionally be decorated with a FuncGroupMarker. If so, the default group and order will be determined by the decorator. Any group or order explicitly passed in to addFuncToGroup will take precedence over the decorator settings.

Parameters
  • func – the function to add

  • group (FuncGroupMarker or None) – the group marker. If the function is decorated with a FuncGoupMarker, that group marker will be the default.

  • order (float or None) – the sorting order. If the function is decorated with a FuncGoupMarker, the order specified in the decorator will be the default.

addLicenseReservation(license, num_tokens=1)

Add a license reservation for this job. This information is used by job control to ensure the job is only started once the required licenses become available.

In a preprocessor, (i.e. before launching the backend), a reservation should be added for each license that will be checked out directly by that backend. Example:

class GlideTask(ComboJobTask):

    @preprocessor
    def _reserveGlideLicense(self):
        # Reserve a Glide license.
        self.addLicenseReservation(license.GLIDE_MAIN)

    def mainFunction(self):
        # Check out the Glide license
        lic = license.License(license.GLIDE_MAIN)

        # ... Do computations requiring Glide ...

        lic.checkin()

Licenses that will be checked out by subjobs of this job do not need reservations added here; subjobs are responsible for their own license reservations.

Parameters
  • license (module-constant from schrodinger.utils.license (e.g. license.AUTODESIGNER)) – a license that will be used by the backend

  • num_tokens (int) – number of tokens for this license reservations

addPostprocessor(func, order=0)

Adds a postproceessor function to this task instance. If the function has been decorated with @postprocessor, the order specified by the decorator will be used.

Parameters
  • func (typing.Callable) – the function to add

  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.

addPreprocessor(func, order=None)

Adds a preproceessor function to this task instance. If the function has been decorated with @preprocessor, the order specified by the decorator will be used as the default.

Parameters
  • func – the function to add

  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.

runPreprocessing(callback=None, calling_context=None)

Run the preprocessors one-by-one. By default, any failing preprocessor will raise a TaskFailure exception and terminate processing. This behavior may be customized by supplying a callback function which will be called after each preprocessor with the result of that preprocessor.

This method is “final” so that all preprocessing logic will be enclosed in the try/finally block.

Parameters
  • callback – a function that takes result and returns a bool that indicates whether to continue on to the next preprocessor

  • calling_context – specify a value here to indicate the context in which this preprocessing is being called. This value will be stored in an instance variable, self.calling_context, which can be accessed from any preprocessor method on this task. Typically this value will be either self.GUI, self.CMDLINE, or None, but any value may be supplied here and checked for in the preprocessor methods. self.calling_context always reverts back to None at the end of runPreprocessing.

runToCmd(skip_preprocessing=False)

Does the same thing as start except it doesn’t actually launch the job. Instead it just returns the final job cmd.

Intended to be used for running jobtasks on JobDJ, which requires a job cmd rather than a task.

sender(self) QObject
senderSignalIndex(self) int
setJob(job: schrodinger.job.jobcontrol.Job)

” Use given jobcontrol.Job to incorporate job results into the task and run postprocessors. Example:

task = FooTask()
cmd = task.runToCommand()
job = jobcontrol.launch_job(cmd)
job.wait()
task.setJob(job)

If the job has not been downloaded, the task will be set to FAILED with a SetJobRuntimeError.

Parameters

jobjobcontrol.Job with results to incorporate into the task.

setObjectName(self, name: str)
classmethod setParamValue(obj, value)

Set the value of a param on an object by specifying the instance and the value:

# Setting the param value of a basic param
a = Atom()
Atom.coord.x.setParamValue(a, 5)
assert a.coord.x == 5

# setParamValue can also be used to set the value of CompoundParams
c = Coord()
c.x = 10
atom.coord.setParamValue(a, c)
assert atom.coord.x == 10
Parameters
  • param – The owner param to set a subparam value of.

  • value – The value to set the subparam value to.

setParent(self, a0: QObject)
setProperty(self, name: str, value: Any) bool
classmethod setReference(param1, param2)

Call this class method from configureParam to indicate that two params should be kept in sync. The initial values will start with the default value of param1. Example:

class Square(CompoundParam):
    width: float = 5
    height: float = 10

    @classmethod
    def configureParam(cls):
        super().configureParam()
        cls.setReference(cls.width, cls.height)

square = Square()
assert square.width == square.height == 5 # Default value of width
                                          # takes priority
square.height = 7
assert square.width == square.height == 7
square.width = 6
assert square.width == square.height == 6
Parameters
  • param1 – The first abstract param to keep synced

  • param2 – The second abstract param. After instantiation, this param will take on the value of param1.

setValue(value=None, **kwargs)

Set the value of this CompoundParam to match value.

Parameters
  • value – The value to set this CompoundParam to. It should be the same type as this CompoundParam.

  • kwargs – For internal use only.

signalsBlocked(self) bool
skip_eq_check()
specifyTaskDir(taskdir_spec)

Specify the taskdir creation behavior. Use one of the following options:

A directory name (string). This may be a relative or absolute path

None - no taskdir is requested. The task will use the CWD as its taskdir

AUTO_TASKDIR - a new subdirectory will be created in the CWD using the task name as the directory name.

TEMP_TASKDIR - a temporary directory will be created in the schrodinger temp dir. This directory is cleaned up when the task is deleted.

Parameters

taskdir_spec – one of the four options listed above

start(skip_preprocessing=False)

This is the main method for starting a task. Start will check if a task is not already running, run preprocessing, and then run the task.

Failures in preprocessing will interrupt the task start, and the task will never enter the RUNNING state.

Parameters

skip_preprocessing (bool) – whether to skip preprocessing. This can be useful if preprocessing was already performed prior to calling start.

startTimer(self, interval: int, timerType: Qt.TimerType = Qt.CoarseTimer) int

class schrodinger.application.phase.shape_screen_reporter.tasks.FilterDBTask(*args, _param_type=<object object>, **kwargs)

Bases: schrodinger.tasks.tasks.ComboSubprocessTask

Task to run filtering on a virtual screening database.

DEFAULT_TASKDIR_SETTING = 2
class Input(*args, _param_type=<object object>, **kwargs)

Bases: schrodinger.models.parameters.CompoundParam

screening_db_file: schrodinger.tasks.tasks.TaskFile

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

When a Param value is set, the valueChanged signal is emitted. Params can be serialized and deserialized to and from JSON. Params can also be nested:

class Atom(CompoundParam):
    coord: Coord
    element: str
property_filters: List[Tuple]

A Param to represent lists. Values of this param will have a mutated signal that will be emitted whenever any mutation method is called.

The constructor optionally takes a item_class keyword argument to specify what type of class the items in the list will be. This information will be used for jsonifying the list if specified.

sel_features: Set[str]

A Param to represent sets. Values of this param will have a mutated signal that will be emitted whenever any elment is added or removed from the set.

The constructor optionally takes a item_class keyword argument to specify what type of class the items in the list will be. This information will be used for jsonifying the set if specified.

diverse_fraction: float

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):

__init__(*args, **kwargs)
addFuncToGroup(func, group=None, order=None)

Adds a function to the specified chain. Typically used for adding functions that are not methods of this object.

The function may optionally be decorated with a FuncGroupMarker. If so, the default group and order will be determined by the decorator. Any group or order explicitly passed in to addFuncToGroup will take precedence over the decorator settings.

Parameters
  • func – the function to add

  • group (FuncGroupMarker or None) – the group marker. If the function is decorated with a FuncGoupMarker, that group marker will be the default.

  • order (float or None) – the sorting order. If the function is decorated with a FuncGoupMarker, the order specified in the decorator will be the default.

addLicenseReservation(license, num_tokens=1)

Add a license reservation for this job. This information is used by job control to ensure the job is only started once the required licenses become available.

In a preprocessor, (i.e. before launching the backend), a reservation should be added for each license that will be checked out directly by that backend. Example:

class GlideTask(ComboJobTask):

    @preprocessor
    def _reserveGlideLicense(self):
        # Reserve a Glide license.
        self.addLicenseReservation(license.GLIDE_MAIN)

    def mainFunction(self):
        # Check out the Glide license
        lic = license.License(license.GLIDE_MAIN)

        # ... Do computations requiring Glide ...

        lic.checkin()

Licenses that will be checked out by subjobs of this job do not need reservations added here; subjobs are responsible for their own license reservations.

Parameters
  • license (module-constant from schrodinger.utils.license (e.g. license.AUTODESIGNER)) – a license that will be used by the backend

  • num_tokens (int) – number of tokens for this license reservations

addPostprocessor(func, order=0)

Adds a postproceessor function to this task instance. If the function has been decorated with @postprocessor, the order specified by the decorator will be used.

Parameters
  • func (typing.Callable) – the function to add

  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.

addPreprocessor(func, order=None)

Adds a preproceessor function to this task instance. If the function has been decorated with @preprocessor, the order specified by the decorator will be used as the default.

Parameters
  • func – the function to add

  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.

max_progress: int

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

When a Param value is set, the valueChanged signal is emitted. Params can be serialized and deserialized to and from JSON. Params can also be nested:

class Atom(CompoundParam):

qprocess

This class can be used to declare a public attribute on a CompoundParam. Declared public attributes can be used without error.

Example usage:

class Coord(CompoundParam):
    x: int
    y: int
    note = NonParamAttribute()

receivers(self, signal: PYQT_SIGNAL) int
removeEventFilter(self, a0: QObject)
replicate()

Create a new task with the same input and settings (but no output)

requestInterruption()

Request the task to stop.

To enable this feature, subclasses should periodically check whether an interruption has been requested and terminate if it has been. If such logic has been included, INTERRUPT_ENABLED should be set to True.

reset(*args, **kwargs)

Resets this compound param to its default value:

class Line(CompoundParam):
    start = Coord(x=1, y=2)
    end = Coord(x=4, y=5)
line = Line()
line.start.x = line.end.x = 10
assert line.start.x == line.end.x == 10
line.reset()
assert line.start.x == 1
assert line.end.x == 4

Any number of abstract params may be passed in to perform a partial reset of only the specified params:

line.start.x = line.end.x = 10
line.reset(Line.start.x)  # resets just start.x
assert line.start.x == 1
assert line.end.x == 10

line.reset(Line.end)      # resets the entire end point
assert line.end.x == 4

line.start.y = line.end.y = 10
line.reset(Line.start.y, Line.end.y)  # resets the y-coord of both
assert line.start.y == 2
assert line.end.y == 5
run()
runBackend()
runCmd(cmd)
runInProcess()
runPreprocessing(callback=None, calling_context=None)

Run the preprocessors one-by-one. By default, any failing preprocessor will raise a TaskFailure exception and terminate processing. This behavior may be customized by supplying a callback function which will be called after each preprocessor with the result of that preprocessor.

This method is “final” so that all preprocessing logic will be enclosed in the try/finally block.

Parameters
  • callback – a function that takes result and returns a bool that indicates whether to continue on to the next preprocessor

  • calling_context – specify a value here to indicate the context in which this preprocessing is being called. This value will be stored in an instance variable, self.calling_context, which can be accessed from any preprocessor method on this task. Typically this value will be either self.GUI, self.CMDLINE, or None, but any value may be supplied here and checked for in the preprocessor methods. self.calling_context always reverts back to None at the end of runPreprocessing.

sender(self) QObject
senderSignalIndex(self) int
setObjectName(self, name: str)
classmethod setParamValue(obj, value)

Set the value of a param on an object by specifying the instance and the value:

# Setting the param value of a basic param
a = Atom()
Atom.coord.x.setParamValue(a, 5)
assert a.coord.x == 5

# setParamValue can also be used to set the value of CompoundParams
c = Coord()
c.x = 10
atom.coord.setParamValue(a, c)
assert atom.coord.x == 10
Parameters
  • param – The owner param to set a subparam value of.

  • value – The value to set the subparam value to.

setParent(self, a0: QObject)
setPrintingOutputToTerminal(print_to_terminal)

Set this task to print StdOut and StdErr output to terminal, or not. This must be set before starting the task to enable terminal output.

Parameters

print_to_terminal (bool) – whether to send process output to terminal

setProperty(self, name: str, value: Any) bool
classmethod setReference(param1, param2)

Call this class method from configureParam to indicate that two params should be kept in sync. The initial values will start with the default value of param1. Example:

class Square(CompoundParam):
    width: float = 5
    height: float = 10

    @classmethod
    def configureParam(cls):
        super().configureParam()
        cls.setReference(cls.width, cls.height)

square = Square()
assert square.width == square.height == 5 # Default value of width
                                          # takes priority
square.height = 7
assert square.width == square.height == 7
square.width = 6
assert square.width == square.height == 6
Parameters
  • param1 – The first abstract param to keep synced

  • param2 – The second abstract param. After instantiation, this param will take on the value of param1.

setValue(value=None, **kwargs)

Parameters
  • value – The value to set this CompoundParam to. It should be the same type as this CompoundParam.

  • kwargs – For internal use only.

signalsBlocked(self) bool
skip_eq_check()
specifyTaskDir(taskdir_spec)

Specify the taskdir creation behavior. Use one of the following options:

A directory name (string). This may be a relative or absolute path

None - no taskdir is requested. The task will use the CWD as its taskdir

AUTO_TASKDIR - a new subdirectory will be created in the CWD using the task name as the directory name.

TEMP_TASKDIR - a temporary directory will be created in the schrodinger temp dir. This directory is cleaned up when the task is deleted.

Parameters

taskdir_spec – one of the four options listed above

Parameters

timeout (NoneType or int) – Amount of time in seconds to wait before timing out. If None or a negative number, this method will wait until the task is finished.

class schrodinger.application.phase.shape_screen_reporter.tasks.StructurePropertyInput(*args, _param_type=<object object>, **kwargs)

Bases: schrodinger.models.parameters.CompoundParam

Variables
  • vsdb_file – The VSDB file from which to extract property values.

  • property_names – The properties to extract from the VSDB.

  • row_nums – The specific VSDB row numbers to query. If empty, property values will be extracted from all rows.

vsdb_file: schrodinger.tasks.tasks.TaskFile

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

class Atom(CompoundParam):
    coord: Coord
    element: str
property_names: List[str]

A Param to represent lists. Values of this param will have a mutated signal that will be emitted whenever any mutation method is called.

The constructor optionally takes a item_class keyword argument to specify what type of class the items in the list will be. This information will be used for jsonifying the list if specified.

row_nums: List[int]

A Param to represent lists. Values of this param will have a mutated signal that will be emitted whenever any mutation method is called.

The constructor optionally takes a item_class keyword argument to specify what type of class the items in the list will be. This information will be used for jsonifying the list if specified.

classmethod setParamValue(obj, value)

Set the value of a param on an object by specifying the instance and the value:

# Setting the param value of a basic param
a = Atom()
Atom.coord.x.setParamValue(a, 5)
assert a.coord.x == 5

# setParamValue can also be used to set the value of CompoundParams
c = Coord()

class Square(CompoundParam):
    width: float = 5
    height: float = 10

    @classmethod
    def configureParam(cls):
        super().configureParam()
        cls.setReference(cls.width, cls.height)

square = Square()
assert square.width == square.height == 5 # Default value of width
                                          # takes priority
square.height = 7
assert square.width == square.height == 7

__init__(*args, **kwargs)
addFuncToGroup(func, group=None, order=None)

Adds a function to the specified chain. Typically used for adding functions that are not methods of this object.

The function may optionally be decorated with a FuncGroupMarker. If so, the default group and order will be determined by the decorator. Any group or order explicitly passed in to addFuncToGroup will take precedence over the decorator settings.

Parameters
  • func – the function to add

  • group (FuncGroupMarker or None) – the group marker. If the function is decorated with a FuncGoupMarker, that group marker will be the default.

  • order (float or None) – the sorting order. If the function is decorated with a FuncGoupMarker, the order specified in the decorator will be the default.

addLicenseReservation(license, num_tokens=1)

Add a license reservation for this job. This information is used by job control to ensure the job is only started once the required licenses become available.

In a preprocessor, (i.e. before launching the backend), a reservation should be added for each license that will be checked out directly by that backend. Example:

class GlideTask(ComboJobTask):

    @preprocessor
    def _reserveGlideLicense(self):
        # Reserve a Glide license.
        self.addLicenseReservation(license.GLIDE_MAIN)

    def mainFunction(self):
        # Check out the Glide license
        lic = license.License(license.GLIDE_MAIN)

        # ... Do computations requiring Glide ...

        lic.checkin()

Licenses that will be checked out by subjobs of this job do not need reservations added here; subjobs are responsible for their own license reservations.

Parameters
  • license (module-constant from schrodinger.utils.license (e.g. license.AUTODESIGNER)) – a license that will be used by the backend

  • num_tokens (int) – number of tokens for this license reservations

addPostprocessor(func, order=0)

Adds a postproceessor function to this task instance. If the function has been decorated with @postprocessor, the order specified by the decorator will be used.

Parameters
  • func (typing.Callable) – the function to add

  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.

addPreprocessor(func, order=None)

Adds a preproceessor function to this task instance. If the function has been decorated with @preprocessor, the order specified by the decorator will be used as the default.

Parameters
  • func – the function to add

  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.

line.start.x = line.end.x = 10
assert line.start.x == line.end.x == 10
line.reset()
assert line.start.x == 1
assert line.end.x == 4

Any number of abstract params may be passed in to perform a partial reset of only the specified params:

line.start.x = line.end.x = 10
line.reset(Line.start.x)  # resets just start.x
assert line.start.x == 1
assert line.end.x == 10

line.reset(Line.end)      # resets the entire end point
assert line.end.x == 4

line.start.y = line.end.y = 10
line.reset(Line.start.y, Line.end.y)  # resets the y-coord of both
assert line.start.y == 2
assert line.end.y == 5

runPreprocessing(callback=None, calling_context=None)

Run the preprocessors one-by-one. By default, any failing preprocessor will raise a TaskFailure exception and terminate processing. This behavior may be customized by supplying a callback function which will be called after each preprocessor with the result of that preprocessor.

This method is “final” so that all preprocessing logic will be enclosed in the try/finally block.

Parameters
  • callback – a function that takes result and returns a bool that indicates whether to continue on to the next preprocessor

  • calling_context – specify a value here to indicate the context in which this preprocessing is being called. This value will be stored in an instance variable, self.calling_context, which can be accessed from any preprocessor method on this task. Typically this value will be either self.GUI, self.CMDLINE, or None, but any value may be supplied here and checked for in the preprocessor methods. self.calling_context always reverts back to None at the end of runPreprocessing.

sender(self) QObject
senderSignalIndex(self) int
setObjectName(self, name: str)
classmethod setParamValue(obj, value)

Set the value of a param on an object by specifying the instance and the value:

# Setting the param value of a basic param
a = Atom()
Atom.coord.x.setParamValue(a, 5)
assert a.coord.x == 5

# setParamValue can also be used to set the value of CompoundParams
c = Coord()
c.x = 10
atom.coord.setParamValue(a, c)
assert atom.coord.x == 10
Parameters
  • param – The owner param to set a subparam value of.

  • value – The value to set the subparam value to.

setParent(self, a0: QObject)
setPrintingOutputToTerminal(print_to_terminal)

Set this task to print StdOut and StdErr output to terminal, or not. This must be set before starting the task to enable terminal output.

Parameters

print_to_terminal (bool) – whether to send process output to terminal

setProperty(self, name: str, value: Any) bool
classmethod setReference(param1, param2)

Call this class method from configureParam to indicate that two params should be kept in sync. The initial values will start with the default value of param1. Example:

class Square(CompoundParam):
    width: float = 5
    height: float = 10

    @classmethod
    def configureParam(cls):
        super().configureParam()
        cls.setReference(cls.width, cls.height)

square = Square()
assert square.width == square.height == 5 # Default value of width
                                          # takes priority
square.height = 7
assert square.width == square.height == 7
square.width = 6
assert square.width == square.height == 6
Parameters
  • param1 – The first abstract param to keep synced

  • param2 – The second abstract param. After instantiation, this param will take on the value of param1.

setValue(value=None, **kwargs)

Set the value of this CompoundParam to match value.

Parameters
  • value – The value to set this CompoundParam to. It should be the same type as this CompoundParam.

  • kwargs – For internal use only.

signalsBlocked(self) bool
skip_eq_check()
specifyTaskDir(taskdir_spec)

Specify the taskdir creation behavior. Use one of the following options:

A directory name (string). This may be a relative or absolute path

None - no taskdir is requested. The task will use the CWD as its taskdir

AUTO_TASKDIR - a new subdirectory will be created in the CWD using the task name as the directory name.

TEMP_TASKDIR - a temporary directory will be created in the schrodinger temp dir. This directory is cleaned up when the task is deleted.

Parameters

taskdir_spec – one of the four options listed above

start(*args, **kwargs)

@overrides: AbstractTask

startTimer(self, interval: int, timerType: Qt.TimerType = Qt.CoarseTimer) int
staticMetaObject = <PyQt6.QtCore.QMetaObject object>
status: Status
statusChanged
statusReplaced
taskDirSetting()

Returns the taskdir spec. See specifyTaskDir() for details.

taskDone
taskFailed
taskStarted
thread(self) QThread
timerEvent(self, a0: QTimerEvent)
toDict()

Return a dictionary version of this CompoundParam. The returned dictionary is fully nested and contains no CompoundParam instances

a = Atom()
a_dict = a.toDict()
assert a_dict['coord']['x'] == 0
assert a_dict['coord'] == {'x':0, 'y':0}
toJson(_mark_version=True)

Create and returns a data structure made up of jsonable items.

Return type

An instance of one the classes from NATIVE_JSON_DATATYPES

toJsonImplementation()

Returns a JSON representation of this value object.

Warning

This should never be called directly.

tr(sourceText: str, disambiguation: typing.Optional[str] = None, n: int = - 1) str
valueChanged
wait(timeout=None)

Block until the task is finished executing or timeout seconds have passed.

Warning

This should not be called directly from GUI code - see PANEL-18317. It is safe to call inside a subprocess or job. Run git grep "task.wait(" to see safe examples annotated with “# OK”.

Parameters

timeout (NoneType or int) – Amount of time in seconds to wait before timing out. If None or a negative number, this method will wait until the task is finished.
