Provides the default implementation for processing inbound frame events and delegates to a Http2FrameListener

This class will read HTTP/2 frames and delegate the events to a Http2FrameListener

This interface enforces inbound flow control functionality through Http2LocalFlowController

DefaultHttp2ConnectionDecoder(Http2Connection connection, Http2ConnectionEncoder encoder, Http2FrameReader frameReader)

public
DefaultHttp2ConnectionDecoder(Http2Connection connection, Http2ConnectionEncoder encoder, Http2FrameReader frameReader, Http2PromisedRequestVerifier requestVerifier)

public
DefaultHttp2ConnectionDecoder(Http2Connection
The Http2Connection associated with this decoder.
connection, Http2ConnectionEncoder
The Http2ConnectionEncoder associated with this decoder.
encoder, Http2FrameReader
Responsible for reading/parsing the raw frames. As opposed to this object which applies h2 semantics on top of the frames.
frameReader, Http2PromisedRequestVerifier
Determines if push promised streams are valid.
requestVerifier, boolean
false to disable automatically applying and sending settings acknowledge frame. The Http2ConnectionEncoder is expected to be an instance of Http2SettingsReceivedConsumer and will apply the earliest received but not yet ACKed SETTINGS when writing the SETTINGS ACKs. true to enable automatically applying and sending settings acknowledge frame.
autoAckSettings)

Create a new instance.
