isSharable
public boolean isSharable()
Description copied from interface:ChannelHandler
Returnstrue
if this handler is sharable and thus can be added to more than oneChannelPipeline
. By default, this method returnsfalse
. If this method returnsfalse
, 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 classMessageToMessageDecoder<DatagramPacket>
- Parameters:
ctx
- theChannelHandlerContext
which thisMessageToMessageDecoder
belongs topacket
- the message to decode to another one- Throws:
Exception
