OperationCallNode extends ActionEdgeSource, ActivityNode, ExecutionEdgeDestination, ExecutionEdgesSource, NamedElement

A virtual Event, which permits an outgoing ECARule to be triggered.

An ActivityOperation may contain any number of OperationCallNodes. Each OperationCallNode must have at least one outgoing ECARule. When the execution flow arrives at an OperationCallNode, each outgoing ECARule will be executed sequentially, according to the priority of each edge.

If the last ECARule executed from the OperationCallNode fails, the execution flow will follow all outgoing failure edges sequentially. Otherwise, the execution flow will follow all outgoing success edges sequentially.

Implementation Notes

All operation calls to Operations contained within Scopes are first evaluated for any onAccess events. [login-handler]
If a OperationCallNode does not have any explicit pass/fail ExecutionEdges defined, then the result value is ignored. [ExecutionFlow]
The result from a OperationCallNode can be used to execute conditional execution paths. [ExecutionFlow]

Constraints

"An OperationCallNode must have exactly one ECARule connecting it to an Operation" [Checks.chk]
"Some of the ECARules defined for this trigger may not be executed, as an unconditional navigation will occur due to the priority order, halting ECARule execution" [Checks.chk] [from ActionEdgeSource]
