public interface InterruptibleChannel
extends Channel sample code for java.nio.channels.Channel definition code for java.nio.channels.Channel

A channel that can be asynchronously closed and interrupted.

A channel that implements this interface is asynchronously closeable: If a thread is blocked in an I/O operation on an interruptible channel then another thread may invoke the channel's close sample code for java.nio.channels.InterruptibleChannel.close() definition code for java.nio.channels.InterruptibleChannel.close() method. This will cause the blocked thread to receive an AsynchronousCloseException sample code for java.nio.channels.AsynchronousCloseException definition code for java.nio.channels.AsynchronousCloseException .

A channel that implements this interface is also interruptible: If a thread is blocked in an I/O operation on an interruptible channel then another thread may invoke the blocked thread's interrupt sample code for java.lang.Thread.interrupt() definition code for java.lang.Thread.interrupt() method. This will cause the channel to be closed, the blocked thread to receive a ClosedByInterruptException sample code for java.nio.channels.ClosedByInterruptException definition code for java.nio.channels.ClosedByInterruptException , and the blocked thread's interrupt status to be set.

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 ClosedByInterruptException sample code for java.nio.channels.ClosedByInterruptException definition code for java.nio.channels.ClosedByInterruptException ; its interrupt status will remain set.

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 instanceof operator.

Method Detail

close sample code for java.nio.channels.InterruptibleChannel.close() definition code for java.nio.channels.InterruptibleChannel.close() 

void close()
           throws IOException sample code for java.io.IOException definition code for java.io.IOException
Closes this channel.

Any thread currently blocked in an I/O operation upon this channel will receive an AsynchronousCloseException sample code for java.nio.channels.AsynchronousCloseException definition code for java.nio.channels.AsynchronousCloseException .

This method otherwise behaves exactly as specified by the Channel sample code for java.nio.channels.Channel.close() definition code for java.nio.channels.Channel.close() interface.
