Constructor & Destructor Documentation

None CDPL.Math.DMatrixTranspose.__init__ ( DMatrixTranspose mt )

Initializes a copy of the DMatrixTranspose instance mt.

Member Function Documentation

◆ getObjectID()

int CDPL.Math.DMatrixTranspose.getObjectID ( )

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

Different Python DMatrixTranspose 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 DMatrixTranspose 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.
