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¶

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:

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

DataClass¶

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()

coord = Coord()
coord.note = "hello" # No error

classmethod fromJsonImplementation(json_dict)¶: Sets the value of this compound param value object from a JSON dict.

Warning

classmethod getJsonBlacklist()¶

Override to customize what params are serialized.

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

..NOTE: Returned abstract params must be direct child params of cls, e.g. cls.name, not cls.coord.x.

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

classmethod getParamValue(obj)¶

Enables access to a param value on a compound param via an abstract param reference:

a = Atom()
assert Atom.coord.x.getParamValue(a) == 0 # ints default to 0
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()
assert c.getSubParam('x') == 0

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()¶: Method to get the version of a particular object. Defaults to the current version of mmshare. This class can be overridden for custom versioning behavior.

# Can be called on an abstract param:
assert Coord.x.owner() == Coord

# ...or on an instance of a CompoundParam
a = Atom()
assert a.coord.owner() == a

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¶

property(self, name: str) → Any¶

pyqtConfigure(...)¶: Each keyword argument is either the name of a Qt property or a Qt signal. For properties the property is set to the given value which should be of an appropriate type. For signals the signal is connected to the given value which should be a callable.

receivers(self, signal: PYQT_SIGNAL) → int¶

removeEventFilter(self, a0: QObject)¶

reset(*abstract_params)¶

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

scoreChanged¶

scoreReplaced¶

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)¶

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.
