encode
Description copied from class:MessageToByteEncoder
Encode a message into aByteBuf
. This method will be called for each written message that can be handled by this encoder.- Specified by:
encode
in classMessageToByteEncoder<DnsQuery>
- Parameters:
ctx
- theChannelHandlerContext
which thisMessageToByteEncoder
belongs tomsg
- the message to encodeout
- theByteBuf
into which the encoded message will be written- Throws:
Exception
- is thrown if an error occurs
-
allocateBuffer
Description copied from class:MessageToByteEncoder
Allocate aByteBuf
which will be used as argument ofMessageToByteEncoder.encode(ChannelHandlerContext, I, ByteBuf)
. Sub-classes may override this method to returnByteBuf
with a perfect matchinginitialCapacity
.- Overrides:
