SpdyFrameCodec

public SpdyFrameCodec(SpdyVersion version,
              int maxChunkSize,
              int maxHeaderSize,
              int compressionLevel,

方法详细资料

beforeAdd

public void beforeAdd(ChannelHandlerContext ctx)
               throws java.lang.Exception

指定者:

beforeAdd 在接口中 LifeCycleAwareChannelHandler

覆盖:

beforeAdd 在类中 FrameDecoder

抛出:

java.lang.Exception

decode

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

从类复制的说明: FrameDecoder

Decodes the received packets so far into a frame. If an sub-class wants to extract a frame out of the buffer it should use the FrameDecoder.extractFrame(ChannelBuffer, int, int) method, to make optimizations easier later.

指定者:

decode 在类中 FrameDecoder

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.

返回:

the decoded frame if a full frame was received and decoded. null if there's not enough data in the buffer to decode a frame.

抛出:

java.lang.Exception

cleanup

protected void cleanup(ChannelHandlerContext ctx,
           ChannelStateEvent e)
                throws java.lang.Exception

从类复制的说明: FrameDecoder

Gets called on FrameDecoder.channelDisconnected(ChannelHandlerContext, ChannelStateEvent) and FrameDecoder.channelClosed(ChannelHandlerContext, ChannelStateEvent)

覆盖:

cleanup 在类中 FrameDecoder

抛出:

从接口复制的说明: ChannelDownstreamHandler

Handles the specified downstream event.

指定者:

参数:

ctx - the context object for this handler

evt - the downstream event to process or intercept

抛出:

java.lang.Exception
