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):
    coord: Coord
    element: str

classmethod ownerChain()

Returns a list of param owners starting from the toplevel param and ending with self. Examples:

foo.bar.atom.coord.ownerChain() will return [foo, bar, atom, coord] where every item is a concrete param.

Foo.bar.atom.coord.x.ownerChain() will return [Foo, Foo.bar, Foo.atom.coord, Foo.atom.coord.x] where every item is an abstract params.

classmethod paramName()

Get the name of the param:

# Can be called on an abstract param:
print(Coord.x.paramName()) # 'x'

# ...or on an instance of a CompoundParam
a = Atom()
a.coord.paramName() # 'coord'
parent(self) QObject

Returns

A list of preprocessors (both decorated methods on the task and external functions that have been added via addPreprocessor)

printDebug(*args)
processFuncChain(chain=None, result_callback=None)

Execute each function in the specified chain sequentially in order.

The result_callback is called after each function with the return value of that function. This can be used to respond to the return value (e.g. present information to the user, get user feedback, log the result, etc.)

The return value of the result_callback determines whether processing will proceeed to the next function.

Parameters
  • chain (FuncChainDecorator) – which chain to process

  • result_callback – the callback that will get called with the result of each function in the chain

Returns

a list of the results from the functions

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:

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

coord = Coord()
coord.x = 4

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.

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.
