Constructor & Destructor Documentation

◆ init() [1/2]

None CDPL.Math.ConstDQuaternionVectorAdapter.__init__ ( ConstDQuaternionVectorAdapter a )

Initializes a copy of the ConstDQuaternionVectorAdapter instance a.

Parameters

a	The `ConstDQuaternionVectorAdapter` instance to copy.

Parameters

e

Member Function Documentation

◆ getObjectID()

int CDPL.Math.ConstDQuaternionVectorAdapter.getObjectID ( )

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

Different Python ConstDQuaternionVectorAdapter 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 ConstDQuaternionVectorAdapter 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.

◆ isEmpty()

bool CDPL.Math.ConstDQuaternionVectorAdapter.isEmpty ( )

Tells whether the view is empty (always False, the view is fixed-size with 4 components).

Returns: False.

◆ getSize()

int CDPL.Math.ConstDQuaternionVectorAdapter.getSize ( )

Returns the dimensionality of the view (always 4).

Returns: 4.

◆ getData()

ConstDQuaternionExpression CDPL.Math.ConstDQuaternionVectorAdapter.getData ( )

Returns a reference to the wrapped quaternion (via its stored closure).

Returns: A reference to the wrapped quaternion closure.

◆ eq() [1/2]

bool CDPL.Math.ConstDQuaternionVectorAdapter.__eq__ ( ConstDQuaternionVectorAdapter a )

◆ getitem()

float CDPL.Math.ConstDQuaternionVectorAdapter.__getitem__ ( int i )

Returns a reference to the quaternion component at index i.

Parameters

i	The zero-based component index.

Returns: A reference to the component.
