public WebSocket13FrameDecoder(boolean expectMaskedFrames,
                               boolean allowExtensions,
                               int maxFramePayloadLength)
```
    Constructor
    
    Parameters:
    
    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.

```
    Description copied from class: ByteToMessageDecoder
    
    Decode the from one Buffer to another. This method will be called till either the input Buffer has nothing to read when return from this method or till nothing was read from the input Buffer.
    
    Specified by:
    
    decode in class ByteToMessageDecoder
    
    Parameters:
    
    ctx - the ChannelHandlerContext which this ByteToMessageDecoder belongs to
    
    in - the Buffer from which to read data
    
    Throws:
    
    Exception - is thrown if an error occurs
