Modifier and Type	Method	Description
`protected void`	`decode(ChannelHandlerContext ctx, DatagramPacket packet)`	Decode from one message to another.

```
public DatagramDnsResponseDecoder()

  - isSharable
```
public boolean isSharable()
```
    Description copied from interface: ChannelHandler
    
    Returns true if this handler is sharable and thus can be added to more than one ChannelPipeline. By default, this method returns false. If this method returns false, you have to create a new handler instance every time you add it to a pipeline because it has unshared state such as member variables.
  - decode
```
protected void decode(ChannelHandlerContext ctx,
                      DatagramPacket packet)
               throws Exception
```
    Description copied from class: MessageToMessageDecoder
    
    Decode from one message to another. This method will be called for each written message that can be handled by this decoder.
    The message will be disposed of after this call.
    Subclasses that wish to sometimes pass messages through, should instead override the MessageToMessageDecoder.decodeAndClose(ChannelHandlerContext, Object) method.
    
    Overrides:
    
    decode in class MessageToMessageDecoder<DatagramPacket>
    
    Parameters:
    
    ctx - the ChannelHandlerContext which this MessageToMessageDecoder belongs to
    
    packet - the message to decode to another one
    
    Throws:
    
    Exception - is thrown if an error occurs
  - decodeResponse
```
protected DnsResponse decodeResponse(ChannelHandlerContext ctx,
                                     DatagramPacket packet)
                              throws Exception
```
    Throws:
    
    Exception
