vB_Trait_NoSerialize
This class is a base intended to contain the backend specific details for converting assertor conditions to query code. The logic is contained in the base class for the time being to allow additional sql backends to override specific functions as much of it will be applicable. We'll most likely need to heavily refactor this when we add a second backend, but that will be more efficiently done when we know what the requirements of that backend really are.
Note that this class is intended to be cached and reused therefore anything that is specific to a particular query needs to be passed as parameter to methods rather than being stored in the class itself. Only items specific to the db backend should be class members.
This is internal to the assertor interface and should not be called from the Application code directly.
