Overloading (Corel Paradox and C++ Cross Reference Guide)

By Mike Prestwood

Corel Paradox versus C++: A side by side comparison between Corel Paradox and C++.

 
Language Details
 

Language Details is kind of a catch all for stuff that didn't make it into language basics nor any other category.

Overloading

[Other Languages] 

Types of overloading include method overloading and operator overloading.

Method Overloading is where different functions with the same name are invoked based on the data types of the parameters passed or the number of parameters. Method overloading is a type of polymorphism and is also known as Parametric Polymorphism.

Operater Overloading allows an operator to behave differently based on the types of values used. For example, in some languages the + operator is used both to add numbers and to concatenate strings. Custom operator overloading is sometimes referred to as ad-hoc polymorphism.

Paradox & Overloading

  • Operator - No.
  • Method - 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 polymorphism (i.e. libMember.Open and libVendor.Open). This is an OOP-like technique for implementing a subtyping-like polymorphism which is also known as inclusion polymorphism.

Also, some developers like to pass an array and then handle the array for a pseudo technique. Although not overloading, it's useful.

C++: 

C++ Overloading

  • Operator - Yes for C++, no for C. Almost all operators can be overloaded for user-defined types
  • Method -
