Constructor & Destructor Documentation

◆ __init__() [1/2]

None CDPL.Math.ConstFVectorRange.__init__ ( ConstFVectorRange  r)

Contructs a copy of the ConstFVectorRange instance r.

Parameters
rThe ConstFVectorRange instance to copy.

Parameters
e
r

Member Function Documentation

◆ getStart()

int CDPL.Math.ConstFVectorRange.getStart ( )

Returns the start index of the viewed range within the wrapped vector.

Returns
The start index of the range.

◆ getObjectID()

int CDPL.Math.ConstFVectorRange.getObjectID ( )

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

Different Python ConstFVectorRange 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 ConstFVectorRange 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.ConstFVectorRange.isEmpty ( )

Tells whether the view is empty (zero-length range).

Returns
True if the range is empty, and False otherwise.

◆ getSize()

int CDPL.Math.ConstFVectorRange.getSize ( )

Returns the size of the view (number of elements covered by the range).

Returns
The number of elements in the view.

◆ getElement()

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

Returns the element at index i of the view.

Parameters
iThe zero-based index within the view.
Returns
The value of the element v(range(i)).

◆ toArray()

object CDPL.Math.ConstFVectorRange.toArray ( )

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

Returns
The generated numpy.ndarray object.

Returns the wrapped vector.

Returns
The wrapped vector closure.

◆ __eq__() [1/2]

bool CDPL.Math.ConstFVectorRange.__eq__ ( ConstFVectorRange  r)

Returns the result of the comparison operation self == r.

Parameters
rThe ConstFVectorRange instance to be compared with.
Returns
The result of the comparison operation.

◆ __eq__() [2/2]

bool CDPL.Math.ConstFVectorRange.__eq__ ( ConstFVectorExpression  e)

Returns the result of the comparison operation self == e.

Parameters

bool CDPL.Math.ConstFVectorRange.__ne__ ( ConstFVectorExpression  e)

Returns the result of the comparison operation self != e.

Parameters
eThe ConstFVectorExpression instance to be compared with.
Returns
The result of the comparison operation.

◆ __call__()

float CDPL.Math.ConstFVectorRange.__call__ ( int  i)

Returns the element at index i of the view.

Parameters
iThe zero-based index within the view.
Returns
The value of the element v(range(i)).

◆ __getitem__()

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

Returns the element at index i of the view.

Parameters
iThe zero-based index within the view.
Returns
The value of the element v(range(i)).

◆ __len__()

int CDPL.Math.ConstFVectorRange.__len__ ( )

Returns the size of the view (number of elements covered by the range).

Returns
The number of elements in the view.

◆ __str__()

str CDPL.Math.ConstFVectorRange.__str__ ( )

Returns a string representation of the ConstFVectorRange instance.

Returns
The generated string representation.

◆ __pos__()

ConstFVectorRange CDPL.Math.ConstFVectorRange.__pos__ ( )
