Method Details

iterParentMethods(self)

source code

adds a getPrimaryIn method to the parent class.

This function will return the value of the primary key in a row passed. The whole thing is a bit dense in that I want to compile that method to avoid having to loop every time it is called. This compilation is done in a descriptor -- ah well, probably it's a waste of time anyway.
