Constructor Detail

WebSocket13FrameDecoder

public WebSocket13FrameDecoder(boolean maskedPayload,
                       boolean allowExtensions)

Constructor with default values

Parameters:

maskedPayload - 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

WebSocket13FrameDecoder

public WebSocket13FrameDecoder(boolean maskedPayload,
                       boolean allowExtensions,
                       long maxFramePayloadLength)

Constructor

Parameters:

maskedPayload - 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.
