Constructor Detail

DatagramDnsQueryDecoder

public DatagramDnsQueryDecoder()

Creates a new decoder with the default record decoder.

DatagramDnsQueryDecoder

public DatagramDnsQueryDecoder(DnsRecordDecoder recordDecoder)

Creates a new decoder with the specified recordDecoder.

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.

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
