implCloseChannel abstract method

Future<void> implCloseChannel()

Closes this channel.

This method is invoked by the {@link #close close} method in order to perform the actual work of closing the channel. This method is only invoked if the channel has not yet been closed, and it is never invoked more than once.

An implementation of this method must arrange for any other thread that is blocked in an I/O operation upon this channel to return immediately, either by throwing an exception or by returning normally.

Implementation
