Member Function Documentation

◆ resize()

None CDPL.Math.LVector.resize	(	int	n,
		int	v = `0`
	)

Resizes the vector to n elements.

Parameters

n	The new element count.

◆ clear()

None CDPL.Math.LVector.clear ( int v = 0 )

Sets every element of the vector to the value v.

◆ getObjectID()

int CDPL.Math.LVector.getObjectID ( )

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

Different Python LVector 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 LVector 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.
