// .NAME vtkMultiProcessStream - stream used to pass data across processes
// using vtkMultiProcessController.
// .SECTION Description
// vtkMultiProcessStream is used to pass data across processes. Using
// vtkMultiProcessStream it is possible to send data whose length is not known
// at the receiving end.
//
// .SECTION Caveats
// Note, stream operators cannot be combined with the Push/Pop array operators.
// For example, if you push an array to the stream,
#ifndef __vtkMultiProcessStream_h
#define __vtkMultiProcessStream_h
#include "vtkParallelCoreModule.h" // For export macro
#include "vtkObject.h"
#include <vector> // needed for vector.
#include <string> // needed for string.
