final Object	attachment() Gets the attached object.
abstract void	cancel() Cancels this key.
abstract SelectableChannel	channel() Gets the channel of this key.
abstract int	interestOps() Gets this key's `interest set`.
abstract SelectionKey	interestOps(int operations) Sets the `interest set` for this key.
final boolean	isAcceptable() Indicates whether this key's channel is interested in the accept operation and is ready to accept new connections.
final boolean	isConnectable() Indicates whether this key's channel is interested in the connect operation and is ready to connect.
final boolean	isReadable() Indicates whether this key's channel is interested in the read operation and is ready to read.
abstract boolean	isValid() Indicates whether this key is valid.
final boolean	isWritable() Indicates whether this key's channel is interested in the write operation and is ready to write.

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals( Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Methods

Added in API level 1

Cancels this key.

A key that has been canceled is no longer valid. Calling this method on an already canceled key does nothing.

Added in API level 1

Indicates whether this key is valid. A key is valid as long as it has not been canceled.
