- Method Detail
  - writeData
```
Future<Void> writeData(ChannelHandlerContext ctx,
                       int streamId,
                       Buffer data,
                       int padding,
                       boolean endStream)
```
    Writes a DATA frame to the remote endpoint. This will result in one or more frames being written to the context.
    
    Parameters:
    
    ctx - the context to use for writing.
    
    streamId - the stream for which to send the frame.
    
    data - the payload of the frame. This will be released by this method.
    
    padding - additional bytes that should be added to obscure the true content size. Must be between 0 and 256 (inclusive). A 1 byte padding is encoded as just the pad length field with value 0. A 256 byte padding is encoded as the pad length field with value 255 and 255 padding bytes appended to the end of the frame.
    
    endStream - indicates if this is the last frame to be sent for the stream.
    
    Returns:
    
    the future for the write.
