Package Summary Overview Summary

### class:CompletionHandler [NONE]
Type Parameters: `V` - The result type of the I/O operation `A` - The type of the object attached to the I/O operation public interface CompletionHandler<V,A> 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. Since: 1.7
