An InstanceVariable is a Field that shares the lifetime of object instances whose type is the Classifier they are associated with. Examples include non-static fields in C++ and Java, and fields of structs in C.

Specification

Metaclass InstanceVariable
Extends Field
Description A Variable associated with instances of a Classifier.
All Superkinds Field, Variable, Node, ModelElement
Specified In Edges
In Edge Predecessor Multiplicity Description
HasVariable Classifier 1 Links a Classifier or Package to one of its Variables.

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.
Specified Out Edges

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.
