AccessConstructor and Description
public
DatagramDnsResponseDecoder()

Method Summary

Modifier and TypeMethod and Description
protected void
decode(ChannelHandlerContext
the ChannelHandlerContext which this MessageToMessageDecoder belongs to
ctx, DatagramPacket
the message to decode to another one
packet)

Overrides io.netty5.handler.codec.MessageToMessageDecoder.decode.

Decode from one message to another.
protected DnsResponse
decodeResponse(ChannelHandlerContext ctx, DatagramPacket packet)

public boolean
isSharable()

Overrides default io.netty5.channel.ChannelHandler.isSharable.

Returns true if this handler is sharable and thus can be added to more than one ChannelPipeline.

protected void decode(ChannelHandlerContext ctx, DatagramPacket packet) throws Exception

Overrides io.netty5.handler.codec.MessageToMessageDecoder.decode.

Doc from io.netty5.handler.codec.MessageToMessageDecoder.decode.

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 decodeAndClose(ChannelHandlerContext, Object) method.

Parameters
ctx:ChannelHandlerContext

the ChannelHandlerContext which this MessageToMessageDecoder belongs to

packet:DatagramPacket

the message to decode to another one

public boolean isSharable()

Overrides default io.netty5.channel.ChannelHandler.isSharable.

Doc from io.netty5.channel.ChannelHandler.isSharable.

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.
