This handler is called when a Worker new Connection is established. A Connection can be either an incoming (ie: something to connected to the server), or outgoing(ie: the server connected to a remote system).

Called periodically on every attached connection handler, this can be used for checking if an ongoing operation has timed out.

Be aware that this is totally independant of a connection's idle timeout, which is only based on the last time there was any I/O.
the frequency at which this method is called. Currently this
is hardcoded to WorkerManager.IdleCheckFrequency, but may become
application dependent in the future.

Pauses writing of the next item in the queue.
Pauses writing of the next item in the queue. If there is currently a message in the process of writing, it will be unaffected. New messages can still be pushed to the queue as long as it is not full
Purge all pending messages

If a message is currently being written, it is not affected
Push a message to be written
Push a message to be written
Pushing a message does not necessarily mean it will be written, but rather that the message is queued to be written. Messages can be queue regardless of the state of the underlying connection, even if the connection is never reconnected. It is up to the caller to determine whether a message should be pushed based on connection state.

the timestamp of when the message was created, defaults to now if not specified
called either when writing has completed or failed
true if the message was successfully enqueued, false if the queue is full
Resumes writing of messages if currently paused, otherwise has no affect

A Request has been made to shutdown this WorkerItem.
A Request has been made to shutdown this WorkerItem. By default this will simply unbind the item from its Worker, but this can be overriden to add in custom shutdown behaviors. Be aware that in some cases this method may not be called and the item will be unbound, such as when an IOSystem is shutting down.
The OutputController maintains all state dealing with writing messages in a controller. It maintains a queue of messages pending write and properly handles writing both regular messages as well as streams.
