// .NAME vtkSubCommunicator - Provides communication on a process group.
|
|
//
|
|
// .SECTION Description
|
|
//
|
|
// This class provides an implementation for communicating on process groups.
|
|
// In general, you should never use this class directly. Instead, use the
|
|
// vtkMultiProcessController::CreateSubController method.
|
|
//
|
|
// .SECTION BUGS
|
|
//
|
|
// Because all communication is delegated to the original communicator,
|
|
// any error will report process ids with respect to the original
|
|
// communicator, not this communicator that was actually used.
|
|
//
