AbstractActivity
abstract public class AbstractActivity extends AbstractExecutionObject implements TimedObject,Serializable(Code)
AbstractActivity represents a simple implementation of the interface ActivityLocal ActivityLocal . It has the following features:

It has no transition restrictions (INLINE, SPLIT, JOIN)

The activity is an implementation activity of the type NO. No SubFlows (SubProcess) or Loops can be expressed with this activity.

The activity supports the StartMode and the FinishMode properties.

The activity cannot act as a requester, i.e. can not start a sub process.

changeAssignment
public void changeAssignment(WfResource oldResource, WfResource newResource) throws InvalidResourceException, AlreadyAssignedException, NotAssignedException(Code)

This method is intended to be used by resource assignment systems for implementing de.danet.an.workflow.localcoreapi.WfAssignment.setAssigneeWfAssignment.setAssignee . Resource assignment systems are responsible for implementing WfAssignment and could therefore perform the reassignment directly; this would, however, leave the generation of notifications unexecuted.

removeAssignment
public void removeAssignment(WfResource resource) throws InvalidResourceException, NotAssignedException(Code)
Removes an assignment for enacting the activity. This method calls the corresponding method of the resource assignment service and creates the appropriate audit event.
