Interface CompletionHandler<V,A>

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>

Disabled: no SafeJ information.

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.
