Parent: | Object |
A thread-safe queue of work for multi-threaded programs.
A {Container} can have multiple threads calling {Container#run} The container ensures that work associated with a single {Connection} or {Listener} is serialized - two threads will never concurrently call handlers associated with the same object.
To have your own code serialized in the same, add a block to the connection‘s {WorkQueue}. The block will be invoked as soon as it is safe to do so.
A {Connection} and the objects associated with it ({Session}, {Sender}, {Receiver}, {Delivery}, {Tracker}) are not thread safe, so if you have multiple threads calling {Container#run} or if you want to affect objects managed by the container from non-container threads you need to use the {WorkQueue}
Add a block of code to be invoked in sequence.
@yield [ ] the block will be invoked with no parameters in the appropriate thread context @note Thread Safe: may be called in any thread. @return [void] @raise [StoppedError] if the queue is closed and cannot accept more work
