Metaclass | ProgramVariable |
---|---|
Extends | Variable |
Description | A Variable declared at top level in a Package (such as the global namespace in C, or any C++ namespace). |
Direct Subkinds | ClassVariable, Enumerator, GlobalVariable, C:StaticLocalVariable |
---|
All Superkinds | Variable, Node, ModelElement |

---|---|---|---|---|
In Edge | Predecessor | Multiplicity | Description | |
HasVariable | Package | 1 | Links a Classifier or Package to one of its Variables. | |
Classifier | 1 | |||
InterproceduralDataFlow | Assignment | ✱ | Represents data flows between Functions, or involving Variables visible to multiple Functions.
| |
Inherited From | In Edge | Predecessor | Multiplicity | Description |
Variable | DataFlow (Edge) | DataFlow (Node) | ✱ | Connects DataFlow nodes to one another and to Variables, linking the origin of data to locations that it is modified or consumed. |

Inherited From | Out Edge | Successor | Multiplicity | Description |
Variable | DataFlow (Edge) | DataFlow (Node) | ✱ | Connects DataFlow nodes to one another and to Variables, linking the origin of data to locations that it is modified or consumed.
|
DefinedAs | TypeAlias | 0..1 | Connects a Variable or DataFlow node which received its Type via a TypeAlias (such as a C/C++ typedef) to that TypeAlias. | |
InstanceVariableWritten | InstanceVariableAssignment | ✱ | Connects a value (DataFlow (Node) or Variable) representing an object instance to an InstanceVariableAssignment representing a write to a field of that object. | |
TypeOf | Type | 1 | Links a Variable or DataFlow node to its Type |
