Class DefaultHttp2RemoteFlowController

java.lang.Object

io.netty.handler.codec.http2.DefaultHttp2RemoteFlowController

All Implemented Interfaces:

io.netty.handler.codec.http2.Http2FlowController, io.netty.handler.codec.http2.Http2RemoteFlowController

@UnstableApi
public class DefaultHttp2RemoteFlowController
extends Object
implements io.netty.handler.codec.http2.Http2RemoteFlowController

Basic implementation of Http2RemoteFlowController.

This class is NOT thread safe. The assumption is all methods must be invoked from a single thread. Typically this thread is the event loop thread for the ChannelHandlerContext managed by this class.
