Data Type

A Data Type is a type whose values have no identity; that is, they are pure values. It is a classifier and inherits the general features of the classifier: visibility, generalizable element properties, and operations.

The modeling tool provides the following predefined data types: boolean, byte, char, date, double, float, int, Integer, Real, long, short, void, and String.

You can also create Enumeration or Primitive Data Types.

To create a new Data Type, including Enumeration or Primitive

• From the Browser, select New from the Class or Create Element from the Package, Subsystem, or Model shortcut menu, and then select Data Type, Enumeration, or Primitive.
• In the Class, Package, Subsystem, and Model Specification widows, the Inner Elements property group, click Create and select a Data Type.

A Data Type can be specified by changing its property values in the Data Type Specification window. Each property is described in the description area on this window.
