Constructor & Destructor Documentation

◆ init() [1/2]

None CDPL.Math.LVectorRange.__init__ ( LVectorRange r )

Contructs a copy of the LVectorRange instance r.

Parameters

r	The `LVectorRange` instance to copy.

Member Function Documentation

◆ getStart()

int CDPL.Math.LVectorRange.getStart ( )

Returns the start index of the viewed range within the wrapped vector.

Returns: The start index of the range.

◆ getObjectID()

int CDPL.Math.LVectorRange.getObjectID ( )

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

Different Python LVectorRange 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 LVectorRange 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.
