## org.jboss.netty.channel
Class DefaultChannelFuture

    java.lang.Object
      org.jboss.netty.channel.DefaultChannelFuture

All Implemented Interfaces:
  ChannelFuture

    public class DefaultChannelFuture

extends Object
implements ChannelFuture

The default `ChannelFuture` implementation. It is recommended to use `Channels.future(Channel)` and `Channels.future(Channel, boolean)` to create a new `ChannelFuture` rather than calling the constructor explicitly.

Constructor Detail

### DefaultChannelFuture

    public DefaultChannelFuture(Channel channel,
                                boolean cancellable)

  Creates a new instance.

  Parameters:
    `channel` - the `Channel` associated with this future
    `cancellable` - `true` if and only if this future can be canceled

Method Detail

### isUseDeadLockChecker

    public static boolean isUseDeadLockChecker()

  Returns `true` if and only if the dead lock checker is enabled.

### setUseDeadLockChecker

    public static void setUseDeadLockChecker(boolean useDeadLockChecker)

  Enables or disables the dead lock checker. It is not recommended to disable the dead lock checker. Disable it at your own risk!

### getChannel

    public Channel getChannel()

  Description copied from interface: `ChannelFuture`
  Returns a channel where the I/O operation associated with this future takes place.

  Specified by:
    `getChannel` in interface `ChannelFuture`

### isDone

    public boolean isDone()

  Description copied from interface: `ChannelFuture`
  Returns `true` if and only if this future is complete, regardless of whether the operation was successful, failed, or cancelled.

  Specified by:
    `isDone` in interface `ChannelFuture`

### isSuccess

    public boolean isSuccess()

  Description copied from interface: `ChannelFuture`
  Returns `true` if and only if the I/O operation was completed successfully.

  Specified by:
    `isSuccess` in interface `ChannelFuture`

### getCause

    public Throwable getCause()

  Description copied from interface: `ChannelFuture`
  Returns the cause of the failed I/O operation if the I/O operation has failed.

  Specified by:
    `getCause` in interface `ChannelFuture`
  Returns:
    the cause of the failure. `null` if succeeded or this future is not completed yet.

### isCancelled

    public boolean isCancelled()

  Description copied from interface: `ChannelFuture`
  Returns `true` if and only if this future was cancelled by a `ChannelFuture.cancel()` method.

  Specified by:
    `isCancelled` in interface `ChannelFuture`

### addListener

    public void addListener(ChannelFutureListener listener)

  Description copied from interface: `ChannelFuture`
  Adds the specified listener to this future. The specified listener is notified when this future is done. If this future is already completed, the specified listener is notified immediately.

  Specified by:
    `addListener` in interface `ChannelFuture`

### removeListener

    public void removeListener(ChannelFutureListener listener)

  Description copied from interface: `ChannelFuture`
  Removes the specified listener from this future. The specified listener is no longer notified when this future is done. If the specified listener is not associated with this future, this method does nothing and returns silently.

  Specified by:
    `removeListener` in interface `ChannelFuture`

### await

    public ChannelFuture await()
                        throws InterruptedException

  Description copied from interface: `ChannelFuture`
  Waits for this future to be completed.

  Specified by:
    `await` in interface `ChannelFuture`
  Throws:
    `InterruptedException` - if the current thread was interrupted

### await

    public boolean await(long timeout,
                         TimeUnit unit)
