This method is called on the event loop thread. It should serialize a write operation object to bytes that can be flushed to the raw nio channel.

Specified by:

writeToBytes in interface ReadWriteHandler

Parameters:

writeOperation - to be converted to bytes

Returns:

the operations to flush the bytes to the channel
