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.ConstFQuaternionVectorAdapter.__init__ ( ConstFQuaternionVectorAdapter  qa)

Contructs a copy of the ConstFQuaternionVectorAdapter instance qa.

Parameters
qaThe ConstFQuaternionVectorAdapter instance to copy.

◆ __init__() [2/2]

None CDPL.Math.ConstFQuaternionVectorAdapter.__init__ ( ConstFQuaternionExpression  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.ConstFQuaternionVectorAdapter.getObjectID ( )

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

Different Python ConstFQuaternionVectorAdapter 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 ConstFQuaternionVectorAdapter 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.ConstFQuaternionVectorAdapter.isEmpty ( )

Tells whether the view is empty (always False).

Returns
False.

◆ getSize()

int CDPL.Math.ConstFQuaternionVectorAdapter.getSize ( )

Returns the dimensionality of the view (always 4).

Returns
4.

◆ getElement()

float CDPL.Math.ConstFQuaternionVectorAdapter.getElement ( int  i)

Returns the quaternion component at index i.

Parameters
iThe zero-based component index (0 = C1, 1 = C2, 2 = C3, 3 = C4).
Returns
The value of the component.
Exceptions
Base.IndexErrorif i is not in the range [0, 3].

◆ toArray()

object CDPL.Math.ConstFQuaternionVectorAdapter.toArray ( )

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

Returns
The generated numpy.ndarray object.
