/**
* A channel that can be asynchronously closed and interrupted.
*
* <p> A channel that implements this interface is <i>asynchronously
* closeable:</i> If a thread is blocked in an I/O operation on an
* interruptible channel then another thread may invoke the channel's {@link
* #close close} method. This will cause the blocked thread to receive an
* {@link AsynchronousCloseException}.
*
* <p> A channel that implements this interface is also <i>interruptible:</i>
* If a thread is blocked in an I/O operation on an interruptible channel then
* another thread may invoke the blocked thread's {@link Thread#interrupt()
* interrupt} method. This will cause the channel to be closed, the blocked
* thread to receive a {@link ClosedByInterruptException}, and the blocked
* thread's interrupt status to be set.
*
* <p> If a thread's interrupt status is already set and it invokes a blocking
* I/O operation upon a channel then the channel will be closed and the thread
* will immediately receive a {@link ClosedByInterruptException}; its interrupt
* status will remain set.
*
* <p> A channel supports asynchronous closing and interruption if, and only
* if, it implements this interface. This can be tested at runtime, if
* necessary, via the <tt>instanceof</tt> operator.
