Extending Base Functions

Since a
function is a restricted and enhanced kind of class, it is possible to inherit an existing function declaration into the declaration of a new function. In this way you can declare the common structure of a set of functions as a partial base function which you subsequently inherit into the functions you want to define.

1 Base Function

OneArgBaseFunction is a partial base function with one argument and one result.

2 Extends Base Class

The functions myTan and addTen inherits the base function. By doing so the code becomes harder to read since the formal parameter list is not available in the functions.

3 myTan Call from a Class

4 addTen Call from a Class
