Examples of org.jbpm.workflow.instance.NodeInstance

org.jbpm.workflow.instance.NodeInstance
Represents a node instance in a RuleFlow. This is the runtime counterpart of a node, containing all runtime state. Node instance classes also contain the logic on what to do when it is being triggered (start executing) or completed (end of execution). @author Kris Verlaenen
