Class NettyPacketDecoder

java.lang.Object
io.netty5.channel.ChannelHandlerAdapter
io.netty5.handler.codec.ByteToMessageDecoder
eu.cloudnetservice.driver.impl.network.netty.codec.NettyPacketDecoder
All Implemented Interfaces:
io.netty5.channel.ChannelHandler
public final class NettyPacketDecoder extends io.netty5.handler.codec.ByteToMessageDecoder
An internal implementation of the packet decoder used for client to server communication. This decoder reverses the encoding steps done in NettyPacketEncoder while ensuring that the channel is open and data was transferred to the component before starting the decoding process.

A packet always contains the following data:

  1. The numeric id of the channel being sent to, by default a var int.
  2. An optional query unique id if the packet is a query.
  3. The data transferred to this component, might be empty.
