Constructor & Destructor Documentation

◆ __init__() [1/2]

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

Contructs a copy of the ULVectorRange instance r.

Parameters
rThe ULVectorRange instance to copy.

◆ __init__() [2/2]

None CDPL.Math.ULVectorRange.__init__ ( ULVectorExpression  e,
Range  r 
)

Member Function Documentation

◆ getStart()

int CDPL.Math.ULVectorRange.getStart ( )

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

Returns
The start index of the range.

◆ getObjectID()

int CDPL.Math.ULVectorRange.getObjectID ( )

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

Different Python ULVectorRange 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 ULVectorRange 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.
