Detailed Description

Constructor & Destructor Documentation

◆ init() [1/2]

None CDPL.Vis.SizeSpecification.__init__ ( SizeSpecification spec )

Initializes a copy of the SizeSpecification instance spec.

Parameters

spec	The SizeSpecification instance to copy.

◆ init() [2/2]

None CDPL.Vis.SizeSpecification.__init__	(	float	value = `0.0`,
		bool	relative = `False`,
		bool	input_scaling = `False`,
		bool	output_scaling = `False`
	)

Constructs a SizeSpecification object with the given attributes.

Parameters

value	The value of the specified size.
relative	`True` if the size specification is relative (proportional) to another size, and `False` otherwise.
input_scaling	`True` if the specified size has to follow input scaling, and `False` otherwise.
output_scaling	`True` if the specified size has to follow output scaling, and `False` otherwise.

Member Function Documentation

◆ getObjectID()

int CDPL.Vis.SizeSpecification.getObjectID ( )

Returns the numeric identifier (ID) of the wrapped C++ class instance.

Different Python SizeSpecification instances may reference the same underlying C++ class instance. The commonly used Python expression a is not b thus cannot tell reliably whether the two SizeSpecification instances a and b reference different C++ objects. The numeric identifier returned by this method allows to correctly implement such an identity test via the simple expression a.getObjectID() != b.getObjectID().

Returns: The numeric ID of the internally referenced C++ class instance.

◆ assign()

SizeSpecification CDPL.Vis.SizeSpecification.assign ( SizeSpecification spec )

Replaces the current state of self with a copy of the state of the SizeSpecification instance spec.

Parameters

spec	The `SizeSpecification` instance to copy.

Returns: self

◆ followsInputScaling()

bool CDPL.Vis.SizeSpecification.followsInputScaling ( )

Tells if the specified size follows input scaling operations.

Returns: True if the specified size follows input scaling operations, and False otherwise.

See also: followInputScaling()

◆ followInputScaling()

None CDPL.Vis.SizeSpecification.followInputScaling ( bool follow )

Specifies whether the specified size has to follow input scaling operations.

Input scaling is a pre-processing step (performed by some other part of the system) where an input size quantity is scaled to fulfill a certain constraint. An example is the scaling of input atom coordinates to obtain a certain average bond length for the 2D depiction of a chemical structure or reaction.

Parameters

follow True if the specified size has to follow input scaling operations, and False otherwise.

◆ followsOutputScaling()

bool CDPL.Vis.SizeSpecification.followsOutputScaling ( )

Tells if the specified size follows output scaling operations.

Returns: True if the specified size follows output scaling operations, and False otherwise.

See also: followOutputScaling()

◆ followOutputScaling()

None CDPL.Vis.SizeSpecification.followOutputScaling ( bool follow )

Specifies whether the specified size has to follow output scaling operations.

Output scaling is a post-processing step (performed by some other part of the system) where an output size quantity is scaled to fulfill a certain constraint. An example is the scaling of output atom coordinates to fit the 2D depiction of a chemical structure or reaction into the viewport area.

Parameters

follow True if the specified size has to follow output scaling operations, and False otherwise.

◆ isRelative()

bool CDPL.Vis.SizeSpecification.isRelative ( )

Tells if the size specification is absolute or relative to another size.

Returns: True if the size specification is relative, and False otherwise.

See also: setRelative()

◆ setRelative()

None CDPL.Vis.SizeSpecification.setRelative ( bool relative )

Specifies if the size specification is absolute or relative to another size.

If the size specification is relative (proportional) to another size, the size value is interpreted as a scaling factor for the absolute value of the other size.

Parameters

relative True if the size specification is relative, and False otherwise.

See also: setValue()

◆ getValue()

float CDPL.Vis.SizeSpecification.getValue ( )

Returns the value of the specified size.

Returns: The value of the specified size.

See also: setValue()

◆ setValue()

None CDPL.Vis.SizeSpecification.setValue ( float value )

Sets value of the specified size.

Parameters

value The value of the specified size.

◆ eq()

bool CDPL.Vis.SizeSpecification.__eq__ ( SizeSpecification spec )

Equality comparison operator.

Parameters

spec	The other `SizeSpecification` object to be compared with.

Returns: True if all attributes compare equal, and False otherwise.

◆ ne()

bool CDPL.Vis.SizeSpecification.__ne__ ( SizeSpecification spec )

Inequality comparison operator.

The result is equivalent to !(self == spec).

Parameters

spec	The other `SizeSpecification` object to be compared with.

Returns: True if one of the attributes compares non-equal, and False otherwise.

◆ str()

str CDPL.Vis.SizeSpecification.__str__ ( )

Returns a string representation of the SizeSpecification instance.

Returns: The generated string representation.
