CompletionHandler
A handler for consuming the result of an asynchronous I/O operation.
The asynchronous channels defined in this package allow a completion
handler to be specified to consume the result of an asynchronous operation.
The completed method is invoked when the I/O operation
completes successfully. The failed method is invoked if the
I/O operations fails. The implementations of these methods should complete
in a timely manner so as to avoid keeping the invoking thread from dispatching
to other completion handlers.
