Constructor & Destructor Documentation

◆ init() [1/2]

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

Contructs a copy of the ConstLQuaternionVectorAdapter instance qa.

Parameters

qa	The `ConstLQuaternionVectorAdapter` instance to copy.

◆ init() [2/2]

None CDPL.Math.ConstLQuaternionVectorAdapter.__init__ ( ConstLQuaternionExpression 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.ConstLQuaternionVectorAdapter.getObjectID ( )

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

Different Python ConstLQuaternionVectorAdapter 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 ConstLQuaternionVectorAdapter 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.ConstLQuaternionVectorAdapter.isEmpty ( )

Tells whether the view is empty (always False).

Returns: False.

◆ getSize()

int CDPL.Math.ConstLQuaternionVectorAdapter.getSize ( )

Returns the dimensionality of the view (always 4).

Returns: 4.

◆ getElement()

int CDPL.Math.ConstLQuaternionVectorAdapter.getElement ( int i )

Returns the quaternion component at index i.

Parameters

i	The zero-based component index (0 = C1, 1 = C2, 2 = C3, 3 = C4).

Returns: The value of the component.

Exceptions

Base.IndexError if i is not in the range [0, 3].

◆ toArray()

object CDPL.Math.ConstLQuaternionVectorAdapter.toArray ( )

Converts the ConstLQuaternionVectorAdapter instance into a corresponding numpy.ndarray object.

Returns: The generated numpy.ndarray object.
