The channel context provides a single object reference that contains all the required information as it is passed between the registered handlers for the lifetime of the request. This object is used to create a thread-safe design so that no other multichannel support objects are required to maintain state.

This singleton class provides a thread-safe registry of the mandatory presentation and request handlers that are required by each device that is implemented by the multichannel interface. This eliminates the overhead required for the object creation for each request.
