Detailed Description

Adapter that exposes a quaternion as a 4-element vector expression (indices map to the components C1, C2, C3, C4).

Constructor & Destructor Documentation

◆ init() [1/2]

None CDPL.Math.DQuaternionVectorAdapter.__init__ ( DQuaternionVectorAdapter qa )

Contructs a copy of the DQuaternionVectorAdapter instance qa.

Parameters

qa	The `DQuaternionVectorAdapter` instance to copy.

◆ init() [2/2]

None CDPL.Math.DQuaternionVectorAdapter.__init__ ( DQuaternionExpression q )

Constructs the adapter wrapping the quaternion q.

Parameters

q	The quaternion to be viewed as a 4-element vector.

Member Function Documentation

◆ getObjectID()

int CDPL.Math.DQuaternionVectorAdapter.getObjectID ( )

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

Different Python DQuaternionVectorAdapter 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 DQuaternionVectorAdapter 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.
