    Returns:
    
    a new buffer with the compressed content. The buffer needs to be released by the receiver
  - decode
```
io.netty.buffer.ByteBuf decode(io.netty.buffer.ByteBuf encoded,
                               int uncompressedSize)
                        throws java.io.IOException
```
    Decompress a buffer.
    The buffer needs to have been compressed with the matching Encoder.
    
    Parameters:
    
    encoded - the compressed content
    
    uncompressedSize - the size of the original content
    
    Returns:
