所有已实现的接口:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler

直接已知子类:

PulsarHandler

public abstract class PulsarDecoder
extends io.netty.channel.ChannelInboundHandlerAdapter

Basic implementation of the channel handler to process inbound Pulsar data.

Please be aware that the decoded protocol command instance passed to a handle* method is cleared and reused for the next protocol command after the method completes. This is done in order to minimize object allocations for performance reasons. It is not allowed to retain a reference to the handle* method parameter command instance after the method returns. If you need to pass an instance of the command instance to another thread or retain a reference to it after the handle* method completes, you must make a deep copy of the command instance.
