What is inheritance?

Rating:

Inheritance is a relationship between two or more classes. In inheritance, one class (called descendant) incorporates all or part of the definition of another class (called ancestor) into its own definition. In PowerBuilder, windows, user objects, and menus can be derived from the existing classes using inheritance.

The use of inheritance provides the following benefits:

  • All changes in the ancestor class are reflected in all its descendants. Therefore, these changes are not required to be made in the descendant classes manually. This saves coding time and makes the application easier to maintain.

  • The descendants inherit the ancestor's scripts. Therefore, the scripts are not required to be re-written.
