All Implemented Interfaces:

ChannelHandler

Direct Known Subclasses:

Http2MultiplexHandler
```
@UnstableApi
public abstract class Http2ChannelDuplexHandler
extends Object
implements ChannelHandler
```
A ChannelHandler providing additional functionality for HTTP/2. Specifically it allows to:
- Create new outbound streams using newStream().
- Iterate over all active streams using forEachActiveStream(Http2FrameStreamVisitor).
The Http2FrameCodec is required to be part of the ChannelPipeline before this handler is added, or else an IllegalStateException will be thrown.
