abstract_class?() Instance Public methods Returns whether this class is an abstract class or not.

base_class() Instance Public methods Returns the class descending directly from ActiveRecord::Base, or an abstract class, if any, in the inheritance hierarchy. If A extends AR::Base, A.base_class will return A. If B descends from A through some arbitrarily deep hierarchy, B.base_class will return A. If B < A and C < B and if A is an #abstract_class then both B.base_class and C.base_class would return B as the answer since A is an abstract_class.

descends_from_active_record?() Instance Public methods Returns true if this does not need STI type condition. Returns false if STI type condition needs to be applied.

new(*args, &block) Instance Public methods Determines if one of the attributes passed in is the inheritance column, and if the inheritance column is attr accessible, it initializes an instance of the given subclass instead of the base class.
