Method Detail

allocateBufferback to summary
protected ByteBuf allocateBuffer(ChannelHandlerContext ctx, AddressedEnvelope<DnsQuery, InetSocketAddress> msg) throws Exception

Allocate a ByteBuf which will be used for constructing a datagram packet. Sub-classes may override this method to return a ByteBuf with a perfect matching initial capacity.

protected void encode(ChannelHandlerContext ctx, AddressedEnvelope<DnsQuery, InetSocketAddress> in, List<Object> out) throws Exception

Implements abstract io.netty.handler.codec.MessageToMessageEncoder.encode.

Doc from io.netty.handler.codec.MessageToMessageEncoder.encode.

Encode from one message to an other. This method will be called for each written message that can be handled by this encoder.

Parameters
ctx:ChannelHandlerContext

the ChannelHandlerContext which this MessageToMessageEncoder belongs to

in:AddressedEnvelope<DnsQuery, InetSocketAddress>

the message to encode to an other one

out:List<Object>

the List into which the encoded msg should be added needs to do some kind of aggregation
