class schrodinger.application.steps.dataclasses.ScoredMol(*args, _param_type=<object object>, **kwargs)

Bases: schrodinger.models.parameters.CompoundParam

mol: rdkit.Chem.rdchem.Mol

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
score: float

Returns

An instance of this class.

Return type

cls

classmethod fromJsonImplementation(json_dict)

Sets the value of this compound param value object from a JSON dict.

Warning

This should never be called directly.

getAbstractParam()

Return the corresponding abstract param for this instance.

classmethod getJsonBlacklist()

Override to customize what params are serialized.

Implementations should return a list of abstract params that should be omitted from serialization.

..NOTE

classmethod getParamSignal(obj, signal_type='Changed')
classmethod getParamValue(obj)

a.coord.x = 3
assert Atom.coord.x.getParamValue(a) == 3
Parameters

param (CompoundParam) – The owner param to get a param value from

classmethod getSubParam(name)

Get the value of a subparam using the string name:

c = Coord()

Note

Using the string name to access params is generally discouraged, but can be useful for serializing/deserializing param data.

Parameters

name (str) – The name of the subparam to get the value for.

classmethod getSubParams()

Return a dictionary mapping subparam names to their values.

getTypeHint()
get_version()
