Detailed Description

A data type for the storage and lookup of arbitrary entity to entity mappings.

Entity3Ds mappings are stored as pairs of references to the mapped Chem.Entity3D objects. Mappings do not have to be unique and multiple mappings of a given entity to other entities are possible. If a mapping entry for a particular entity does not exist, the methods Entity3DMapping.getValue() and Entity3DMapping.operator[]() return a None reference to indicate that the lookup of the mapped entity has failed.

Constructor & Destructor Documentation

◆ __init__()

None CDPL.Chem.Entity3DMapping.__init__ ( Entity3DMapping  mapping)

Initializes a copy of the Entity3DMapping instance mapping.

Parameters
mappingThe Entity3DMapping instance to copy.

Member Function Documentation

◆ getObjectID()

int CDPL.Chem.Entity3DMapping.getObjectID ( )

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

Different Python Entity3DMapping 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 Entity3DMapping 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.

◆ getSize()

int CDPL.Chem.Entity3DMapping.getSize ( )
Returns

◆ isEmpty()

bool CDPL.Chem.Entity3DMapping.isEmpty ( )
Returns

◆ assign()

Entity3DMapping CDPL.Chem.Entity3DMapping.assign ( Entity3DMapping  map)

Replaces the current state of self with a copy of the state of the Entity3DMapping instance map.

Parameters
mapThe Entity3DMapping instance to copy.
Returns
self
