datatype

sub-package containing the definition of the predefined data types

DataType

A data type is a type whose instances are identified only by their value. A DataType may contain attributes to support the modeling of structured data types [source: UML superstructure v2.2]

Common Types: AbstractNamedElement, ModelElement, Namespace, NamedElement, CapellaElement, TraceableElement, PublishableElement

Known Sub Types: BooleanType, Enumeration, StringType, NumericType, PhysicalQuantity

BooleanType

A boolean is an instance of PrimitiveType. In the metamodel, Boolean defines an enumeration that denotes a logical condition. Its enumeration literals are:

  • true - The Boolean condition is satisfied.
  • false - The Boolean condition is not satisfied [source: UML superstructure v2.2]

Common Types: AbstractNamedElement, ModelElement, Namespace, NamedElement, CapellaElement, TraceableElement, PublishableElement

Enumeration

An enumeration is a kind of data type, whose instances may be any of a number of user-defined enumeration literals [source: UML superstructure v2.2]

PhysicalQuantity

A Physical Quantity is a measurable value of a physical property of a thing or a movement. It referes to a Unit.

A Dimension (SysML notion of Physical Quantity) is a kind of quantity that may be stated by means of defined units. For example, the dimension of length may be measured by units of meters, kilometers, or feet [source: SysML specification v1.1]

Common Types: AbstractNamedElement, ModelElement, Namespace, NamedElement, CapellaElement, TraceableElement, PublishableElement
