Java OOP Details

Polymorphism

A coding technique where the same named function, operator, or object behaves differently depending on outside input or influences. Usually implemented as parameter overloading where the same named function is overloaded with other versions that are called either with a different type or number of parameters. Polymorphism is a general coding technique and other specific implementations are common such as inheritance, operator overloading, and interfaces.

Languages Focus

Many languages support built-in polymorphism such as a "+" operator that can add both integers and decimals. The following documents the ability to implement developer defined polymorphism.

Built-in: In ObjectPAL, polymorphism is the capability of the built-in objects to act differently depending on the context in which they are being used. For example, Table.Open and TCursor.Open. The Open method works differently depending on the object type used.

Custom: No. However, you can have the same named method or procedure so long as they are in different libraries. This is important if you use libraries in a class-like OOP way and wish to implement some form of interfaces-like polymorphism (i.e. libMember.GetName and libVendor.GetName).
