构造器详细资料

WebSocket08FrameDecoder

public WebSocket08FrameDecoder(boolean expectMaskedFrames,
                               boolean allowExtensions,
                               int maxFramePayloadLength)

Constructor

参数:

expectMaskedFrames - Web socket servers must set this to true processed incoming masked payload. Client implementations must set this to false.

allowExtensions - Flag to allow reserved extension bits to be used or not

maxFramePayloadLength - Maximum length of a frame's payload. Setting this to an appropriate value for you application helps check for denial of services attacks.

public WebSocket08FrameDecoder(boolean expectMaskedFrames,
                               boolean allowExtensions,
                               int maxFramePayloadLength,
                               boolean allowMaskMismatch)

Constructor

参数:

expectMaskedFrames - Web socket servers must set this to true processed incoming masked payload. Client implementations must set this to false.

allowExtensions - Flag to allow reserved extension bits to be used or not

maxFramePayloadLength - Maximum length of a frame's payload. Setting this to an appropriate value for you application helps check for denial of services attacks.

allowMaskMismatch - When set to true, frames which are not masked properly according to the standard will still be accepted.

WebSocket08FrameDecoder

public WebSocket08FrameDecoder(WebSocketDecoderConfig decoderConfig)

Constructor

参数:

decoderConfig - Frames decoder configuration.

方法详细资料

decode

protected void decode(ChannelHandlerContext ctx,
                      ByteBuf in,
                      java.util.List<java.lang.Object> out)
               throws java.lang.Exception

从类复制的说明: ByteToMessageDecoder

Decode the from one ByteBuf to an other. This method will be called till either the input ByteBuf has nothing to read when return from this method or till nothing was read from the input ByteBuf.

指定者:

decode 在类中 ByteToMessageDecoder

参数:

ctx - the ChannelHandlerContext which this ByteToMessageDecoder belongs to

in - the ByteBuf from which to read data

out - the List to which decoded messages should be added

抛出:

java.lang.Exception - is thrown if an error occurs

checkCloseFrameBody

protected void checkCloseFrameBody(ChannelHandlerContext ctx,
                                   ByteBuf buffer)
