Detailed Description

thread safe dispatcher reference that can be passed around.

A shared dispatchable holds either a copy of another dispatchable or the dispatcher itself is only accessible by constructing a shared_dispatchable::DispatcherPtr.

Note:

Multiple reads of the same object are threadsafe, multiple writes not:

    // threadsafe
    shared_dispatchable::DispatcherPtr dispatcher(shareddisp);
    
    // not threadsafe
    shareddisp = mydisp;
