Inheritance diagram for vtkSharedMemoryCommunicator:
Detailed Description
Provides communication using shared memory.This class is used together with vtkThreadedController for communication between threads. Once initialized, it creates one communicator per thread. The messages to be sent are copied to the message list of the appropriate communicator by the sending thread and then read by the receiving thread. Mutexes are used to ensure safe access to the data structures. By default, when an object is sent, it is copied with DeepCopy. This behavior can be changed by un-setting ForceDeepCopy.
