Short Class Definition

There is a short syntax for defining classes, commonly used to introduce more informative type names for existing classes.

class Voltage = Real(Unit = "V");

The same thing can be written using the keyword type instead:

type Voltage = Real;

The short class definition is the only way to introduce a "class" name for an array type:

type Matrix10 = Real [10, 10];

A short class definition is in most cases just a shorter syntax for defining a class that could just as well be defined using the standard inheritance syntax:

type Voltage extends Real(unit = "V", min = -220.0, max = 220.0); end Voltage;

Which is just the same as this:

type Voltage = Real(unit = "V", min = -220.0, max = 220.0);

Writing array types is done this short way:

type Force3 = Real[3](unit={"N","N","N"});
