- Constructor Detail
  - CompressionHandler
```
public CompressionHandler(Supplier<? extends Compressor> compressorSupplier)
```
    Creates a new instance.
    
    Parameters:
    
    compressorSupplier - the Supplier that is used to create the Compressor.
  - CompressionHandler
```
public CompressionHandler(Supplier<? extends Compressor> compressorSupplier,
                          long closeWriteTimeout,
                          TimeUnit closeWriteTimeoutUnit,
                          boolean discardBytesAfterFinished)
```
    Creates a new instance.
    
    Parameters:
    
    compressorSupplier - the Supplier that is used to create the Compressor.
    
    closeWriteTimeout - the amount to wait before we will close even tho the write of the trailer was not finished yet.
    
    closeWriteTimeoutUnit - the unit of the timeout.
    
    discardBytesAfterFinished - true if the bytes should be discarded after the Compressor finished the compression of the whole stream.

  - handlerAdded
```
public void handlerAdded(ChannelHandlerContext ctx)
                  throws Exception
```
    Description copied from interface: ChannelHandler
    
    Gets called after the ChannelHandler was added to the actual context and it's ready to handle events.
    
    Specified by:
    
    handlerAdded in interface ChannelHandler
    
    Throws:
    
    Exception
  - handlerRemoved
```
public void handlerRemoved(ChannelHandlerContext ctx)
                    throws Exception
```
    Description copied from interface: ChannelHandler
    
    Gets called after the ChannelHandler was removed from the actual context and it doesn't handle events anymore.
    
    Specified by:
    
    handlerRemoved in interface ChannelHandler
    
    Throws:
    
    Exception
  - channelInactive
```
public void channelInactive(ChannelHandlerContext ctx)
                     throws Exception
```
    Description copied from interface: ChannelHandler
    
    The Channel of the ChannelHandlerContext was registered is now inactive and reached its end of lifetime.
    
    Specified by:
    
    channelInactive in interface ChannelHandler
    
    Throws:
    
    Exception
  - write
```
public Future<Void> write(ChannelHandlerContext ctx,
                          Object msg)
```
    Description copied from interface: ChannelHandler
    
    Called once a write operation is made. The write operation will write the messages through the ChannelPipeline. Those are then ready to be flushed to the actual Channel once Channel.flush() is called.
    
    Specified by:
    
    write in interface ChannelHandler
    
    Parameters:
    
    ctx - the ChannelHandlerContext for which the write operation is made
    
    msg - the message to write
    
    Returns:
    
    the Future which will be notified once the operation completes.
  - close
```
public Future<Void> close(ChannelHandlerContext ctx)
```
    Description copied from interface: ChannelHandler
    
    Called once a close operation is made.
    
    Specified by:
    
    close in interface ChannelHandler
    
    Parameters:
    
    ctx - the ChannelHandlerContext for which the close operation is made
    
    Returns:
    
    the Future which will be notified once the operation completes.
