构造器详细资料

WebSocket00FrameDecoder

public WebSocket00FrameDecoder()

WebSocket00FrameDecoder

public WebSocket00FrameDecoder(long maxFrameSize)

Creates a new instance of WebSocketFrameDecoder with the specified maxFrameSize. If the client sends a frame size larger than maxFrameSize, the channel will be closed.

参数:

maxFrameSize - the maximum frame size to decode

方法详细资料

decode

protected java.lang.Object decode(ChannelHandlerContext ctx,
                      Channel channel,
                      ChannelBuffer buffer,
                      VoidEnum state)
                           throws java.lang.Exception

从类复制的说明: ReplayingDecoder

Decodes the received packets so far into a frame.

指定者:

decode 在类中 ReplayingDecoder<VoidEnum>

参数:

ctx - the context of this handler

channel - the current channel

buffer - the cumulative buffer of received packets so far. Note that the buffer might be empty, which means you should not make an assumption that the buffer contains at least one byte in your decoder implementation.

state - the current decoder state (null if unused)

返回:

the decoded frame

抛出:

java.lang.Exception
