Constructor & Destructor Documentation

◆ __init__() [1/2]

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

Contructs a copy of the ConstLVectorRange instance r.

Parameters
rThe ConstLVectorRange instance to copy.

Parameters
e
r

Member Function Documentation

◆ getStart()

int CDPL.Math.ConstLVectorRange.getStart ( )

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

Returns
The start index of the range.

◆ getObjectID()

int CDPL.Math.ConstLVectorRange.getObjectID ( )

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

Different Python ConstLVectorRange 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 ConstLVectorRange 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.ConstLVectorRange.isEmpty ( )

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

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

◆ getSize()

int CDPL.Math.ConstLVectorRange.getSize ( )

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

Returns
The number of elements in the view.

◆ getElement()

int CDPL.Math.ConstLVectorRange.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.ConstLVectorRange.toArray ( )

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

Returns
The generated numpy.ndarray object.

◆ getData()

ConstLVectorExpression CDPL.Math.ConstLVectorRange.getData ( )

Returns the wrapped vector.

Returns
The wrapped vector closure.

◆ __eq__() [1/2]

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

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

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

◆ __eq__() [2/2]

bool CDPL.Math.ConstLVectorRange.__eq__ ( ConstLVectorExpression  e)

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

Parameters

bool CDPL.Math.ConstLVectorRange.__ne__ ( ConstLVectorExpression  e)

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

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

◆ __call__()

int CDPL.Math.ConstLVectorRange.__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__()

int CDPL.Math.ConstLVectorRange.__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.ConstLVectorRange.__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.ConstLVectorRange.__str__ ( )

Returns a string representation of the ConstLVectorRange instance.

Returns
The generated string representation.

◆ __pos__()

ConstLVectorRange CDPL.Math.ConstLVectorRange.__pos__ ( )
