Member Function Documentation

◆ clear()

None CDPL.Math.Matrix2D.clear ( float v = 0.0 )

Parameters

v

◆ getObjectID()

int CDPL.Math.Matrix2D.getObjectID ( )

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

Different Python Matrix2D 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 Matrix2D 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.
