InterruptibleChannel

public interface InterruptibleChannel
implements Channel

java.nio.channels.InterruptibleChannel


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.

Summary

abstract void close()

Closes this channel.

Public methods

close

added in API level 1
public abstract void close ()

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.

Throws
IOException If an I/O error occurs
