Deprecated Fields

Field and Description
io.netty.channel.ChannelOption.DATAGRAM_CHANNEL_ACTIVE_ON_REGISTRATION

Deprecated Methods

Method and Description
io.netty.channel.ChannelFlushPromiseNotifier.add(ChannelPromise, int) use ChannelFlushPromiseNotifier.add(ChannelPromise, long)
io.netty.channel.ChannelHandlerContext.attr(AttributeKey<T>) Use AttributeMap.attr(AttributeKey)
io.netty.bootstrap.AbstractBootstrap.channelFactory(ChannelFactory<? extends C>) Use AbstractBootstrap.channelFactory(io.netty.channel.ChannelFactory) instead.
io.netty.bootstrap.ServerBootstrap.childGroup() Use ServerBootstrap.config() instead.
io.netty.channel.group.ChannelGroup.deregister() This method will be removed in the next major feature release. Deregister all Channels in this group from their EventLoop. Please note that this operation is asynchronous as ChannelOutboundInvoker.deregister() is.
io.netty.channel.group.ChannelGroup.deregister(ChannelMatcher) This method will be removed in the next major feature release. Deregister all Channels in this group from their EventLoop that are matched by the given ChannelMatcher. Please note that this operation is asynchronous as ChannelOutboundInvoker.deregister() is.
io.netty.channel.ChannelHandler.exceptionCaught(ChannelHandlerContext, Throwable) is part of ChannelInboundHandler
io.netty.channel.group.ChannelGroup.flushAndWrite(Object) Use ChannelGroup.writeAndFlush(Object) instead.
