Examples with ChannelOutboundBuffer io.netty.channel.ChannelOutboundBuffer used on opensource projects

Example 1 with ChannelOutboundBuffer

use of io.netty.channel.ChannelOutboundBuffer in project netty by netty.

the class IdleStateHandler method hasOutputChanged.

     * with {@link #observeOutput} enabled and there has been an observed change in the
     * {@link ChannelOutboundBuffer} between two consecutive calls of this method.
