Package org.jbpm.pvm.impl Description

Bidirectional relations

In this process model thoughout the pvm codebase, there are several bidirectional relations. By convention, the bidirectional relations are maintained on the many side. This means that when you call for example CompositeElementImpl.addNode(org.jbpm.pvm.impl.NodeImpl), that method will also update the inverse pointer by invoking the ProcessElementImpl.setProcessDefinition(org.jbpm.pvm.impl.ProcessDefinitionImpl) setter. Setter methods will be plain setter methods and they will NOT update the inverse reference. (that would cause an infinite loop).

In the same spirit, there is the convention that the many side of bidirection relations provide factory methods for the related objects. Those factory methods will also establish the bidirectional relation. E.g. CompositeElementImpl.createNode(String).
