Creates a new encoder with the specified recordEncoder.

Method Detail

encode

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

Specified by:

encode in class io.netty.handler.codec.MessageToMessageEncoder<io.netty.channel.AddressedEnvelope<DnsQuery,InetSocketAddress>>

Throws:

Exception

allocateBuffer

protected io.netty.buffer.ByteBuf allocateBuffer(io.netty.channel.ChannelHandlerContext ctx,
                                                 io.netty.channel.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.

Throws:

Exception
