Constructor	Description
`DatagramDnsResponseEncoder()`	Creates a new encoder with the default record encoder.
`DatagramDnsResponseEncoder(DnsRecordEncoder recordEncoder)`	Creates a new encoder with the specified `recordEncoder`.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`protected Buffer`	`allocateBuffer(ChannelHandlerContext ctx, AddressedEnvelope<DnsResponse,InetSocketAddress> msg)`	Allocate a `Buffer` which will be used for constructing a datagram packet.
`protected void`	`encode(ChannelHandlerContext ctx, AddressedEnvelope<DnsResponse,InetSocketAddress> in, List<Object> out)`	Encode from one message to another.
`boolean`	`isSharable()`	Returns `true` if this handler is sharable and thus can be added to more than one `ChannelPipeline`.

  - DatagramDnsResponseEncoder
```
public DatagramDnsResponseEncoder()
```
    Creates a new encoder with the default record encoder.
  - DatagramDnsResponseEncoder
```
public DatagramDnsResponseEncoder(DnsRecordEncoder recordEncoder)
```
    Creates a new encoder with the specified recordEncoder.
- Method Detail
  - 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.
  - encode
```
protected void encode(ChannelHandlerContext ctx,
                      AddressedEnvelope<DnsResponse,InetSocketAddress> in,
                      List<Object> out)
               throws Exception
```
    Description copied from class: MessageToMessageEncoder
    
    Encode from one message to another. This method will be called for each written message that can be handled by this encoder.
    The message will be disposed of after this call.
    Subclasses that wish to sometimes pass messages through, should instead override the MessageToMessageEncoder.encodeAndClose(ChannelHandlerContext, Object, List) method.
    
    Overrides:
    
    encode in class MessageToMessageEncoder<AddressedEnvelope<DnsResponse,InetSocketAddress>>
    
    Parameters:
    
    ctx - the ChannelHandlerContext which this MessageToMessageEncoder belongs to.
    
    in - the message to encode to another one.
    
    out - the List into which produced output messages should be added.
    
    Throws:
    
    Exception - is thrown if an error occurs.
  - allocateBuffer
```
protected Buffer allocateBuffer(ChannelHandlerContext ctx,
                                AddressedEnvelope<DnsResponse,InetSocketAddress> msg)
                         throws Exception
```
    Allocate a Buffer which will be used for constructing a datagram packet. Sub-classes may override this method to return a Buffer with a perfect matching initial capacity.
    
    Throws:
    
    Exception
