Motivation: There is no way for a ChannelHandler to check if the passed in ChannelPromise for a write(...) call is a VoidChannelPromise. This is a problem as some handlers need to add listeners to the ChannelPromise which is not possible in the case of a VoidChannelPromise. Modification: - Introduce ChannelFuture.isVoid() which will return true if it is not possible to add listeners or wait on the result. - Add ChannelPromise.unvoid() which allows to create a ChannelFuture out of a void ChannelFuture which supports all the operations. Result: It's now easy to write ChannelHandler implementations which also works when a void ChannelPromise is used. |
