Is it possible to write to Netty channel without creating unnecessary ChannelFuture? (Without generating unnecessary object for GC…)
If you really wish you don’t want to create a
ChannelFuture, you can do this for Netty 3:Channels.succeededFuture(..)returns a channel-local singleton object. However, you should never add a listener to the returned future because it’s already complete.In Netty 4, you can use void promise:
ChannelHandlerContext.voidPromise()returns a dummy singleton promise which is never fulfilled. The operations like adding a listener or waiting until it is fulfilled will fail immediately.
