Generic Functions and Methods

---

A generic function is a collection of function objects. Each element in the collection is called a method. Each method corresponds to a class. When you call a generic function, you pass an instance as the first argument. The SKILL++ Object System uses the class of the first argument to determine which methods to evaluate.

To distinguish them from SKILL++ Object System generic functions, SKILL functions are called simple functions. The SKILL++ Object System provides the following functions.

• defgeneric function to declare a generic function
• defmethod function to declare a method

This topic provides a list of generic functions and methods.
