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.LQuaternionVectorAdapter.__init__ ( LQuaternionVectorAdapter  qa)

Contructs a copy of the LQuaternionVectorAdapter instance qa.

Parameters
qaThe LQuaternionVectorAdapter instance to copy.

◆ __init__() [2/2]

None CDPL.Math.LQuaternionVectorAdapter.__init__ ( LQuaternionExpression  q)

Constructs the adapter wrapping the quaternion q.

Parameters
qThe quaternion to be viewed as a 4-element vector.

Member Function Documentation

◆ getObjectID()

int CDPL.Math.LQuaternionVectorAdapter.getObjectID ( )

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

Different Python LQuaternionVectorAdapter 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 LQuaternionVectorAdapter 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.
