Method Detail

incomingFrame

public void incomingFrame(Frame frame)

isRsv1User

public boolean isRsv1User()

Indicates use of RSV1 flag for indicating deflation is in use.

Also known as the "COMP" framing header bit

Specified by:

isRsv1User in interface Extension

Overrides:

isRsv1User in class AbstractExtension

Returns:

true if extension uses RSV1 for its own purposes.

isTextDataDecoder

public boolean isTextDataDecoder()

Indicate that this extensions is now responsible for TEXT Data Frame compliance to the WebSocket spec.

Specified by:

isTextDataDecoder in interface Extension

Overrides:

isTextDataDecoder in class AbstractExtension

Returns:

true if extension will process TEXT Data Frames, false if extension makes no modifications of TEXT Data Frames. If false, the parser/generator is now free to validate the conformance to spec of TEXT Data Frames.

outgoingFrame

public void outgoingFrame(Frame frame,
                 WriteCallback callback)

setConfig

public void setConfig(ExtensionConfig config)

Overrides:

setConfig in class AbstractExtension

toString

public String toString()

Overrides:

toString in class AbstractExtension
