Directed inheritance

PRPC provides two types of class inheritance, both of which allow rules of ancestor classes to be inherited:

• Directed inheritance — Allows you to name a parent class, choosing a name that's not related to the name of this class
• Pattern inheritance — The system determines the name of the parent class is based on an initial portion or substring of the name of the class. Segments of the name are delimited by a dash (-) character.

For example, the PegaSample-CustomerRequest class, part of the PegaSample sample application, employs directed inheritance. Its directed parent class is Work-Cover-DupByCus. Based on pattern inheritance, the parent class is Work-Object-.

The class rule controls how inheritance works for a class.

Use the Class Inheritance display to confirm which classes are ancestor classes to a specific class, and the order in which PRPC searches these classes during rule resolution (using both pattern inheritance and directed inheritance). On this display, a solid arrow () indicates a directed inheritance relationship. The arrowhead identifies the class of the immediate directed parent.
