encode
protected void encode(ChannelHandlerContext ctx, AddressedEnvelope<DnsResponse,java.net.InetSocketAddress> in, java.util.List<java.lang.Object> out) throws java.lang.Exception
Description copied from class:MessageToMessageEncoder
Encode from one message to an other. This method will be called for each written message that can be handled by this encoder.- Specified by:
encode
in classMessageToMessageEncoder<AddressedEnvelope<DnsResponse,java.net.InetSocketAddress>>
- Parameters:
ctx
- theChannelHandlerContext
which thisMessageToMessageEncoder
belongs toin
- the message to encode to an other oneout
- theList
into which the encoded msg should be added needs to do some kind of aggregation- Throws:
java.lang.Exception
- is thrown if an error occurs
-
allocateBuffer
protected ByteBuf allocateBuffer(ChannelHandlerContext ctx, AddressedEnvelope<DnsResponse,java.net.InetSocketAddress> msg) throws java.lang.Exception
Allocate aByteBuf
which will be used for constructing a datagram packet. Sub-classes may override this method to return aByteBuf
with a perfect matching initial capacity.- Throws:
java.lang.Exception
