Field Detail

as

private AssignmentService as

The reference to the server side service implementation.

---

rmsf

private static de.danet.an.workflow.spis.rms.ResourceManagementServiceFactory rmsf

The associated resource management service factory.

---

rmsCache

private static de.danet.an.workflow.spis.rms.ResourceManagementService rmsCache

The resource management service associated with the factory.

---

rms

private de.danet.an.workflow.spis.rms.ResourceManagementService rms

The resource management service associated with this service.

---

finderCache

private static java.util.HashMap finderCache

A cache with activity finders for optimization.

---

ejbConfigured

private static boolean ejbConfigured

Constructor Detail

StandardResourceAssignmentService

public StandardResourceAssignmentService(AssignmentService assignSvc,
                                         de.danet.an.workflow.spis.rms.ResourceManagementServiceFactory rmsFac)

Constructs a new resource assignment service.

Method Detail

getRms

private de.danet.an.workflow.spis.rms.ResourceManagementService getRms()

Get the resource management service. This can only be done lazily, as the resource management service needs a resource assignment service and we would end up in loop if we wouldn't do it lazily.

---

configureEJB

private void configureEJB()
                   throws java.rmi.RemoteException

Configure the associated EJB. Configuration currently consists of setting the resource management service. This can't be done in the constructor as we need the resource management service in order to do so. The resource management service must, however, be created lazily as stated in getRms 55 .

---

writeObject

private void writeObject(java.io.ObjectOutputStream out)
                  throws java.io.IOException

Serializing requires some preparation. We do not assume that service factories are serializable. Therefore we cannot transfer rmsf (that's why it is declared transient). If we have not obtained the service before serialization, we can therefore no longer obtain it after deserialization. So just make sure we have it now.

---

finderIndex

protected long finderIndex(de.danet.an.workflow.spis.ras.ActivityFinder finder)
                    throws java.rmi.RemoteException

Get the finder index for a finder.

---

asResource

public de.danet.an.workflow.omgcore.WfResource asResource(java.security.Principal principal)
                                                   throws java.rmi.RemoteException,
                                                          de.danet.an.workflow.spis.ras.NoSuchResourceException

Given a principal, return the workflow resource associated with this principal. This implementation simply delegates the request to the resource management service.

Specified by:

asResource in interface de.danet.an.workflow.spis.ras.ResourceAssignmentService

---

resourceByKey

public de.danet.an.workflow.omgcore.WfResource resourceByKey(java.lang.String key)
                                                      throws de.danet.an.workflow.spis.ras.NoSuchResourceException,
                                                             java.rmi.RemoteException

Given the key of a WfResource (obtained with resourceKey()>resourceKey() 55 ), return the workflow resource associated with this key.

This method is implemented by simply calling resourceByKey>resourceByKey 55 of the underlying resource management service.

Specified by:

resourceByKey in interface de.danet.an.workflow.spis.ras.ResourceAssignmentService

---

autoAssignResources

public void autoAssignResources(de.danet.an.workflow.spis.ras.ActivityFinder finder,
                                java.lang.String actId,
                                de.danet.an.workflow.omgcore.WfActivity activity,
                                java.security.Principal principal,
                                de.danet.an.workflow.spis.ras.Participant participant)
                         throws java.rmi.RemoteException

Triggers the automatic assignment of resources to an activity that is about to become ready.

If resSel is of type string, the following cases are handled by the assignment service:

!:currentUser

Assigns the current user.

In all other cases the parameter resSel is simply passed through to the resource selection service 55 .

Specified by:

autoAssignResources in interface de.danet.an.workflow.spis.ras.ResourceAssignmentService

addAssignment

public void addAssignment(de.danet.an.workflow.spis.ras.ActivityFinder finder,
