| Channels that implement this interface can be asynchronously closed and
interrupted.
A channel that can be asynchronously closed permits that a thread blocked on
an I/O operation (the I/O thread) can be released by another thread calling
the channel's {@link #close()} method. The I/O thread will throw an
{@link AsynchronousCloseException} and the channel will be closed.
A channel that is interruptible permits a thread blocked on an I/O operation
(the I/O thread) to be interrupted by another thread (by invoking
{@link Thread#interrupt()} on the I/O thread). When the I/O thread is
interrupted it will throw a {@link ClosedByInterruptException}, it will have
its interrupted status set and the channel will be closed. If the I/O thread
attempts to make an I/O call with the interrupt status set the call will
immediately fail with a {@link ClosedByInterruptException}. |
