Direct Subclasses: WriteVariableAction, ReadVariableAction, ClearVariableAction

Class Precedence List: VariableAction, Action, ExecutableNode, ActivityNode, RedefinableElement, NamedElement, Element

Properties:

variable : Variable (1 1); -- source VariableAction
context : Classifier (0 1); -- source Action
input : InputPin (0 *); -- source Action
isLocallyReentrant : Boolean (1 1); -- source Action
localPostcondition : Constraint (0 *); -- source Action
localPrecondition : Constraint (0 *); -- source Action
output : OutputPin (0 *); -- source Action
handler : ExceptionHandler (0 *); -- source ExecutableNode

A set of exception handlers that are examined if an uncaught exception propagates to the outer level of the executable node.
