Class FixedHttp2ConnectionDecoder

java.lang.Object

io.grpc.netty.FixedHttp2ConnectionDecoder

All Implemented Interfaces:

Http2ConnectionDecoder, Closeable, AutoCloseable

@UnstableApi
public class FixedHttp2ConnectionDecoder
extends Object
implements Http2ConnectionDecoder

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
