## Interface InterruptibleChannel

- All Superinterfaces:
    AutoCloseable, Channel, Closeable
  All Known Implementing Classes:
    AbstractInterruptibleChannel, AbstractSelectableChannel, DatagramChannel, FileChannel, Pipe.SinkChannel, Pipe.SourceChannel, SelectableChannel, ServerSocketChannel, SocketChannel

      public interface InterruptibleChannel
      extends 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` method. This will cause the blocked thread to receive an `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` method. This will cause the channel to be closed, the blocked thread to receive a `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`; 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.

    - #### close

          void close()
              throws IOException

      Closes this channel.

      Any thread currently blocked in an I/O operation upon this channel will receive an `AsynchronousCloseException`.

      This method otherwise behaves exactly as specified by the `Channel` interface.

      Specified by:
        `close` in interface `AutoCloseable`
      Specified by:
        `close` in interface `Channel`
      Specified by:
        `close` in interface `Closeable`
      Throws:
        `IOException` - If an I/O error occurs
