类 WebSocketClientExtensionHandler

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.netty.channel.ChannelDuplexHandler

io.netty.handler.codec.http.websocketx.extensions.WebSocketClientExtensionHandler

所有已实现的接口:

ChannelHandler, ChannelInboundHandler, ChannelOutboundHandler

直接已知子类:

WebSocketClientCompressionHandler

public class WebSocketClientExtensionHandler
extends ChannelDuplexHandler

This handler negotiates and initializes the WebSocket Extensions. This implementation negotiates the extension with the server in a defined order, ensures that the successfully negotiated extensions are consistent between them, and initializes the channel pipeline with the extension decoder and encoder.

public WebSocketClientExtensionHandler(WebSocketClientExtensionHandshaker... extensionHandshakers)

Constructor

参数:

extensionHandshakers - The extension handshaker in priority order. A handshaker could be repeated many times with fallback configuration.

方法详细资料

write

public void write(ChannelHandlerContext ctx,
                  java.lang.Object msg,
                  ChannelPromise promise)
           throws java.lang.Exception

从类复制的说明: ChannelDuplexHandler

Calls ChannelOutboundInvoker.write(Object, ChannelPromise) to forward to the next ChannelOutboundHandler in the ChannelPipeline. Sub-classes may override this method to change behavior.

指定者:

write 在接口中 ChannelOutboundHandler

覆盖:

write 在类中 ChannelDuplexHandler

参数:

ctx - the ChannelHandlerContext for which the write operation is made

msg - the message to write

promise - the ChannelPromise to notify once the operation completes

抛出:

java.lang.Exception - thrown if an error occurs

channelRead

public void channelRead(ChannelHandlerContext ctx,
                        java.lang.Object msg)
                 throws java.lang.Exception

从类复制的说明: ChannelInboundHandlerAdapter

Calls ChannelHandlerContext.fireChannelRead(Object) to forward to the next ChannelInboundHandler in the ChannelPipeline. Sub-classes may override this method to change behavior.

指定者:

channelRead 在接口中 ChannelInboundHandler

覆盖:

channelRead 在类中 ChannelInboundHandlerAdapter

抛出:

java.lang.Exception
