Constructor & Destructor Documentation

CommunicationPattern()

LinearAlgebra::TpetraWrappers::CommunicationPattern::CommunicationPattern	(	const IndexSet &	vector_space_vector_index_set,
		const IndexSet &	read_write_vector_index_set,
		const MPI_Comm	communicator
	)

Reinitialize the communication pattern. The first argument vector_space_vector_index_set is the index set associated to a VectorSpaceVector object. The second argument read_write_vector_index_set is the index set associated to a ReadWriteVector object.
