  - decoderEnforceMaxConsecutiveEmptyDataFrames
```
public HttpToHttp2ConnectionHandlerBuilder decoderEnforceMaxConsecutiveEmptyDataFrames(int maxConsecutiveEmptyFrames)
```
    Description copied from class: AbstractHttp2ConnectionHandlerBuilder
    
    Sets the maximum number of consecutive empty DATA frames (without end_of_stream flag) that are allowed before the connection is closed. This allows to protect against the remote peer flooding us with such frames and so use up a lot of CPU. There is no valid use-case for empty DATA frames without end_of_stream flag. 0 means no protection should be applied.

```
    Description copied from class: AbstractHttp2ConnectionHandlerBuilder
    
    Sets the maximum number RST frames that are allowed per window before the connection is closed. This allows to protect against the remote peer flooding us with such frames and so use up a lot of CPU. 0 for any of the parameters means no protection should be applied.
    
    Overrides:

  - encoderEnforceMaxRstFramesPerWindow

```
    Description copied from class: AbstractHttp2ConnectionHandlerBuilder
    
    Sets the maximum number RST frames that are allowed per window before the connection is closed. This allows to protect against the remote peer that will trigger us to generate a flood of RST frames and so use up a lot of CPU. 0 for any of the parameters means no protection should be applied.

  - decoupleCloseAndGoAway
```
public HttpToHttp2ConnectionHandlerBuilder decoupleCloseAndGoAway(boolean decoupleCloseAndGoAway)
```
    Description copied from class: AbstractHttp2ConnectionHandlerBuilder
    
    Determine if the Channel.close() should be coupled with goaway and graceful close.
    
    Overrides:
    
    decoupleCloseAndGoAway in class AbstractHttp2ConnectionHandlerBuilder<HttpToHttp2ConnectionHandler,HttpToHttp2ConnectionHandlerBuilder>
    
    Parameters:
    
    decoupleCloseAndGoAway - true to make Channel.close() directly close the underlying transport, and not attempt graceful closure via GOAWAY.
    
    Returns:
    
    this.
  - flushPreface
```
public HttpToHttp2ConnectionHandlerBuilder flushPreface(boolean flushPreface)
```
    Description copied from class: AbstractHttp2ConnectionHandlerBuilder
    
    Determine if the Preface should be automatically flushed when the Channel becomes active or not.
    Client may choose to opt-out from this automatic behavior and manage flush manually if it's ready to send request frames immediately after the preface. It may help to avoid unnecessary latency.
    
    Overrides:
    
    flushPreface in class AbstractHttp2ConnectionHandlerBuilder<HttpToHttp2ConnectionHandler,HttpToHttp2ConnectionHandlerBuilder>
    
    Parameters:
    
    flushPreface - true to automatically flush, false otherwise.
    
    Returns:
    
    this.

```
    Description copied from class: AbstractHttp2ConnectionHandlerBuilder
    Implement this method to create a new Http2ConnectionHandler or its subtype instance.
    The return of this method will be subject to the following:
    
    AbstractHttp2ConnectionHandlerBuilder.frameListener(Http2FrameListener) will be set if not already set in the decoder
    
    AbstractHttp2ConnectionHandlerBuilder.gracefulShutdownTimeoutMillis(long) will always be set
