Method Summary

Modifier and TypeMethod and Description
pack-priv final Object
attachForeignChannel(final Channel channel, FileDescriptor fd)

Implements abstract sun.nio.ch.AsynchronousChannelGroupImpl.attachForeignChannel.

Attaches a foreign channel to this group.

pack-priv final void
closeAllChannels()

Implements abstract sun.nio.ch.AsynchronousChannelGroupImpl.closeAllChannels.

Closes all channels in the group

pack-priv final void
detachForeignChannel(Object key)

Implements abstract sun.nio.ch.AsynchronousChannelGroupImpl.detachForeignChannel.

Detaches a foreign channel from this group.

pack-priv final boolean
isEmpty()

Implements abstract sun.nio.ch.AsynchronousChannelGroupImpl.isEmpty.

Returns true if there are no channels in the group

protected void
preUnregister(int fd)

Callback method for implementations that need special handling when fd is removed (currently only needed in the AIX-Port - see AixPollPort.java).

pack-priv final void
register(int fd, Port.PollableChannel ch)

Register channel identified by its file descriptor

pack-priv abstract void
startPoll(int fd, int events)

Register file descriptor with polling mechanism for given events.

pack-priv final void
unregister(int fd)

Unregister channel identified by its file descriptor
