CancelNode extends ActivityNode, ExecutionEdgeDestination

Specifies that the current ActivityOperation did not execute successfully, or the ActivityPredicate must return false.

An ActivityOperation may contain any number of CancelNodes. When the execution flow arrives at a CancelNode, the execution of the operation will finish, however the execution will be marked as a failure. The failure handler of the ECARule that executed the Operation will be called to handle this failure.

The CancelNode element is based on the UML FinalNode (flow final) model element.

Implementation Notes

A failing operation within an ActivityOperation wrapped with a ECARulenamed 'fail' will redirect to the destination Frame instead. [testFailingOperation()]
An operation flow that goes to a failure node will cause the operation to fail. [testFailingOperation()]

Attributes

exceptionText : EString (optional)
Within an ActivityOperation, this message will be provided to the developer as a failure reason if this exception is not caught by a failure handler.

Inherited Attributes

generatedRule : EString (optional)
To assist in debugging, this attribute may be populated with the name of the model completion rule that created this element. More extensive traceability support may be provided in the future.
id : EString (optional)
A unique identifier for this model element. Should be globally unique.
isGenerated : EBoolean (optional)
Set to true if the current element has been generated.
