load (
        self,
        ob,
        attrName,
        )

Load ob at least with attrName

Note that a lazy loader is allowed to load all the attributes it knows how to, as long as it only overwrites itself in the object's dictionary. That is, if an attribute to be read has already been written to, it should not reload that attribute.

This method is not required to return a value, and it can ignore the attrName parameter as long as it is certain that the attrName attribute will be loaded.
