org.jboss.netty.handler.codec.oneone
类 OneToOneDecoder

java.lang.Object
  org.jboss.netty.handler.codec.oneone.OneToOneDecoder

所有已实现的接口：

ChannelHandler, ChannelUpstreamHandler

直接已知子类：

Base64Decoder, ProtobufDecoder, StringDecoder, ZlibDecoder

public abstract class OneToOneDecoder
extends java.lang.Object
implements ChannelUpstreamHandler

Transforms a received message into another message. Please note that this decoder must be used with a proper FrameDecoder such as DelimiterBasedFrameDecoder or you must implement proper framing mechanism by yourself if you are using a stream-based transport such as TCP/IP. A typical setup for TCP/IP would be:

 ChannelPipeline pipeline = ...;

 // Decoders
 pipeline.addLast("frameDecoder", new DelimiterBasedFrameDecoder(80, Delimiters.nulDelimiter()));
 pipeline.addLast("customDecoder", new OneToOneDecoder() { ... });

 // Encoder
 pipeline.addLast("customEncoder", new OneToOneEncoder() { ... });
