Member Function Documentation

virtual void vtkCommunicator::Operation::Function	(	const void *	A,
		void *	B,
		vtkIdType	length,
		int	datatype
	)		[pure virtual]

Subclasses must overload this method, which performs the actual operations. The methods should first do a reintepret cast of the arrays to the type suggestsed by datatype (which will be one of the VTK type identifiers like VTK_INT, etc.). Both arrays are considered top be length entries. The method should perform the operation A*B (where * is a placeholder for whatever operation is actually performed) and store the result in B. The operation is assumed to be associative. Commutativity is specified by the Commutative method.

virtual int vtkCommunicator::Operation::Commutative

(

)

[pure virtual]

Subclasses override this method to specify whether their operation is commutative. It should return 1 if commutative or 0 if not.
