Detailed Description

Memory-efficient immutable vector where all elements have the same value of type unsigned long.

Constructor & Destructor Documentation

◆ init() [1/2]

None CDPL.Math.ULScalarVector.__init__ ( ULScalarVector v )

Constructs a copy of the scalar vector v.

Parameters

v	The scalar vector to copy.

◆ init() [2/2]

None CDPL.Math.ULScalarVector.__init__	(	int	n,
		int	v = `0`
	)

Constructs a scalar vector of size n in which every element equals v.

Parameters

n	The element count.
v	The common element value.

Member Function Documentation

◆ resize()

None CDPL.Math.ULScalarVector.resize ( int n )

Resizes the logical element count to n.

Parameters

n	The new element count.

◆ getObjectID()

int CDPL.Math.ULScalarVector.getObjectID ( )

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

Different Python ULScalarVector 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 ULScalarVector 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.ULScalarVector.isEmpty ( )

Tells whether the vector has zero logical size.

Returns: True if the logical size is zero, and False otherwise.

◆ getSize()

int CDPL.Math.ULScalarVector.getSize ( )

Returns the logical element count.

Returns: The element count.

◆ getElement()

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

Returns the common element value.

Parameters

i	The zero-based element index.

Returns: The common element value.

Exceptions

Base.IndexError if i is out of range.

◆ toArray()

object CDPL.Math.ULScalarVector.toArray ( )

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

Returns: The generated numpy.ndarray object.

See also: [NUMPY]

◆ assign()

ULScalarVector CDPL.Math.ULScalarVector.assign ( ULScalarVector v )

Copy-assigns the size and common value from v.

Parameters

v	The source scalar vector.

Returns: self.

◆ swap()

None CDPL.Math.ULScalarVector.swap ( ULScalarVector v )

Swaps the size and common value with v.

Parameters

v	The scalar vector to swap with.

◆ eq() [1/2]

bool CDPL.Math.ULScalarVector.__eq__ ( ULScalarVector v )

Returns: The result of the comparison operation.

◆ ne() [2/2]

bool CDPL.Math.ULScalarVector.__ne__ ( ConstULVectorExpression e )

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

Parameters

e	The `ConstULVectorExpression` instance to be compared with.

Returns: The result of the comparison operation.

◆ call()

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

Returns the common element value.
