A representation of the model object '
Variable
'.
Variables are elements for passing data between actions indirectly. A local variable stores values shared by the actions within a structured activity group but not accessible outside it. The output of an action may be written to a variable and read for the input to a subsequent action, which is effectively an indirect data flow path. Because there is no predefined relationship between actions that read and write variables, these actions must be sequenced by control flows to prevent race conditions that may occur between actions that read or write the same variable.
A variable is considered a connectable element.
The following features are supported:

getActivityScope
Activity getActivityScope()
- Returns the value of the '
Activity Scope
' container reference.
It is bidirectional and its opposite is '
Variable'.
This feature subsets the following features:
An activity that owns the variable.
-
-
-
Returns:
- the value of the 'Activity Scope' container reference.
-
See Also:
-
setActivityScope(Activity),
UMLPackage.getVariable_ActivityScope(),
Activity.getVariables()
setActivityScope
void setActivityScope(
Activity value)
- Sets the value of the '
Activity Scope' container reference.
-
-
-
Parameters:
-
value - the new value of the 'Activity Scope' container reference. -
See Also:
-
getActivityScope()
getScope
StructuredActivityNode getScope()
- Returns the value of the '
Scope
' container reference.
It is bidirectional and its opposite is '
Variable'.
This feature subsets the following features:
A structured activity node that owns the variable.
-
-
-
Returns:
- the value of the 'Scope' container reference.
-
See Also:
-
setScope(StructuredActivityNode),
UMLPackage.getVariable_Scope(),
StructuredActivityNode.getVariables()
setScope
void setScope(
StructuredActivityNode value)
- Sets the value of the '
Scope' container reference.
-
-
-
Parameters:
-
value - the new value of the 'Scope' container reference. -
See Also:
-
getScope()
validateOwned
boolean validateOwned(org.eclipse.emf.common.util.DiagnosticChain diagnostics,
java.util.Map<java.lang.Object,java.lang.Object> context)
-
A variable is owned by a StructuredNode or Activity, but not both.
true
-
-
-
Parameters:
-
diagnostics - The chain of diagnostics to which problems are to be appended. -
context - The cache of context-specific information.
isAccessibleBy
boolean isAccessibleBy(
Action a)
-
The isAccessibleBy() operation is not defined in standard UML. Implementations should define it to specify which actions can access a variable.
result = true
