org.apache.tinkerpop.gremlin.server.handler.WsGremlinBinaryRequestDecoder

All Implemented Interfaces:

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

@ChannelHandler.Sharable
public class WsGremlinBinaryRequestDecoder
extends io.netty.handler.codec.MessageToMessageDecoder<io.netty.handler.codec.http.websocketx.BinaryWebSocketFrame>

Decodes the contents of a BinaryWebSocketFrame. Binary-based frames assume that the format is encoded in the first initial bytes of the message. From there the proper serializer can be chosen and the message can then be deserialized.
