All Known Implementing Classes:

DecoratingHttp2ConnectionDecoder, DefaultHttp2ConnectionDecoder
```
@UnstableApi
public interface Http2ConnectionDecoder
extends Closeable
```
Handler for inbound traffic on behalf of Http2ConnectionHandler. Performs basic protocol conformance on inbound frames before calling the delegate Http2FrameListener for application-specific processing. Note that frames of an unknown type (i.e. HTTP/2 extensions) will skip all protocol checks and be given directly to the listener for processing.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`close()`
`Http2Connection`	`connection()`	Provides direct access to the underlying connection.
`void`	`decodeFrame(ChannelHandlerContext ctx, Buffer in)`	Called by the `Http2ConnectionHandler` to decode the next frame from the input buffer.
`Http2LocalFlowController`	`flowController()`	Provides the local flow controller for managing inbound traffic.
`Http2FrameListener`	`frameListener()`	Get the `Http2FrameListener` which will be notified when frames are decoded.
`void`	`frameListener(Http2FrameListener listener)`	Set the `Http2FrameListener` which will be notified when frames are decoded.
`void`	`lifecycleManager(Http2LifecycleManager lifecycleManager)`	Sets the lifecycle manager.
`Http2Settings`	`localSettings()`	Gets the local settings for this endpoint of the HTTP/2 connection.
`boolean`	`prefaceReceived()`	Indicates whether or not the first initial `SETTINGS` frame was received from the remote endpoint.

- Method Detail
  - lifecycleManager
```
void lifecycleManager(Http2LifecycleManager lifecycleManager)
```
    Sets the lifecycle manager. Must be called as part of initialization before the decoder is used.
  - connection
```
Http2Connection connection()
```
    Provides direct access to the underlying connection.
  - flowController
```
Http2LocalFlowController flowController()
```
    Provides the local flow controller for managing inbound traffic.
  - frameListener
```
void frameListener(Http2FrameListener listener)
```
    Set the Http2FrameListener which will be notified when frames are decoded.
    This must be set before frames are decoded.
  - frameListener
```
Http2FrameListener frameListener()
```
    Get the Http2FrameListener which will be notified when frames are decoded.
  - decodeFrame
```
void decodeFrame(ChannelHandlerContext ctx,
                 Buffer in)
          throws Http2Exception
```
    Called by the Http2ConnectionHandler to decode the next frame from the input buffer.
    
    Throws:
    
    Http2Exception
  - localSettings
```
Http2Settings localSettings()
```
    Gets the local settings for this endpoint of the HTTP/2 connection.
  - prefaceReceived
```
boolean prefaceReceived()
```
    Indicates whether or not the first initial SETTINGS frame was received from the remote endpoint.
  - close
```
void close()
```
