Member Function Documentation

◆ getStart()

int CDPL.Math.ConstULVectorRange.getStart ( )

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

Returns: The start index of the range.

◆ getObjectID()

int CDPL.Math.ConstULVectorRange.getObjectID ( )

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

Different Python ConstULVectorRange 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 ConstULVectorRange 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.ConstULVectorRange.isEmpty ( )

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

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

◆ getSize()

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

Returns the element at index i of the view.

Parameters

i	The zero-based index within the view.

Returns: The value of the element v(range(i)).

◆ toArray()

object CDPL.Math.ConstULVectorRange.toArray ( )

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

Returns: The generated numpy.ndarray object.

See also: [NUMPY]

◆ getData()

Returns the wrapped vector.

Returns: The wrapped vector closure.

◆ eq() [1/2]

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

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

Parameters

r	The `ConstULVectorRange` instance to be compared with.

Returns: The result of the comparison operation.

◆ eq() [2/2]

Returns: The result of the comparison operation.

◆ call()

int CDPL.Math.ConstULVectorRange.__call__ ( int i )

Returns the element at index i of the view.

Parameters

i	The zero-based index within the view.

Returns: The value of the element v(range(i)).

◆ getitem()

int CDPL.Math.ConstULVectorRange.__getitem__ ( int i )

Returns the element at index i of the view.

Parameters

i	The zero-based index within the view.

Returns: The number of elements in the view.

◆ str()

str CDPL.Math.ConstULVectorRange.__str__ ( )

Returns a string representation of the ConstULVectorRange instance.

Returns: The generated string representation.

◆ pos()

ConstULVectorRange CDPL.Math.ConstULVectorRange.__pos__ ( )

Returns self.

Returns: self.

◆ neg()

ConstULVectorExpression CDPL.Math.ConstULVectorRange.__neg__ ( )
