Examples of org.eclipse.bpel.model.Link

org.eclipse.bpel.model.Link
A representation of the model object 'Link'. Specifies the synchronization dependencies between activities in a flow. Each activity can be the source and/or target of any number of links. Links establish a predecessor/successor relationship between activities. Activities that are the source of a link are predecessors of activities that are targets of the same link. Parallel execution of activities in a flow is synchronized by requiring that all the source activities of an activity must complete before corresponding target activities of the same link can run. When an activity completes, all activities that are targets of links for which this activity is a source are now candidates for execution (assuming all their predecessor activities have completed).
The following features are supported:
- {@link org.eclipse.bpel.model.Link#getName Name}
- {@link org.eclipse.bpel.model.Link#getSources Sources}
- {@link org.eclipse.bpel.model.Link#getTargets Targets}
@see org.eclipse.bpel.model.BPELPackage#getLink() @model @generated
