Class GremlinResponseFrameEncoder

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelOutboundHandlerAdapter

io.netty.handler.codec.MessageToMessageEncoder<ResponseMessage>

org.apache.tinkerpop.gremlin.server.handler.GremlinResponseFrameEncoder

All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelOutboundHandler

@ChannelHandler.Sharable
public class GremlinResponseFrameEncoder
extends io.netty.handler.codec.MessageToMessageEncoder<ResponseMessage>

Ensures that any ResponseMessage manages to get converted to a Frame. By converting to Frame downstream protocols can treat the generic Frame any way it wants (e.g. write it back as a byte array, websocket frame, etc).
