- Method Detail
  - getWindowSize
```
default int getWindowSize()
```
    Returns:
    
    the current connection window size or -1 for HTTP/1.x
  - setWindowSize
```
default HttpConnection setWindowSize(int windowSize)
```
    Update the current connection wide window size to a new size.
    Increasing this value, gives better performance when several data streams are multiplexed
    This is not implemented for HTTP/1.x.
    
    Parameters:
    
    windowSize - the new window size
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - goAway
```
default HttpConnection goAway(long errorCode)
```
    Like goAway(long, int) with a last stream id -1 which means to disallow any new stream creation.
  - goAway
```
default HttpConnection goAway(long errorCode,
                              int lastStreamId)
```
    Like goAway(long, int, Buffer) with no buffer.
  - goAway
```
HttpConnection goAway(long errorCode,
                      int lastStreamId,
                      Buffer debugData)
```
    Send a go away frame to the remote endpoint of the connection.
    - a GOAWAY frame is sent to the to the remote endpoint with the errorCode and debugData
    - any stream created after the stream identified by lastStreamId will be closed
    - for an errorCode is different than 0 when all the remaining streams are closed this connection will be closed automatically
    This is not implemented for HTTP/1.x.
    Parameters:
    
    errorCode - the GOAWAY error code
    
    lastStreamId - the last stream id
    
    debugData - additional debug data sent to the remote endpoint
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - goAwayHandler
```
HttpConnection goAwayHandler(Handler<GoAway> handler)
```
    Set an handler called when a GOAWAY frame is received.
    This is not implemented for HTTP/1.x.
    
    Parameters:
    
    handler - the handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - shutdownHandler
```
HttpConnection shutdownHandler(Handler<Void> handler)
```
    Set an handler called when a GOAWAY frame has been sent or received and all connections are closed.
    This is not implemented for HTTP/1.x.
    
    Parameters:
    
    handler - the handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - shutdown
```
default HttpConnection shutdown()
```
    Initiate a graceful connection shutdown, the connection is taken out of service and closed when all current requests are processed, otherwise after 30 seconds the connection will be closed. Client connection are immediately removed from the pool.
    - HTTP/2 connections will send a go away frame immediately to signal the other side the connection will close
    - HTTP/1.x client connection supports this feature
    - HTTP/1.x server connections do not support this feature
    Returns:
    
    a reference to this, so the API can be used fluently
  - shutdown
```
HttpConnection shutdown(long timeoutMs)
```
    Like shutdown() but with a configurable timeout value.
    
    Parameters:
