Constructor Detail

DefaultResource

public DefaultResource(ResourceAssignmentContext cbh,
                       java.lang.String key,
                       java.lang.String name)

The constructor. It ensures that a valid factory exists.

Parameters:

key - the resource's key

name - the resource's name

Method Detail

resourceKey

public java.lang.String resourceKey()
                             throws java.rmi.RemoteException

Retrieve the key of a resource.

Specified by:

resourceKey in interface WfResource

Returns:

key of resource

Throws:

java.rmi.RemoteException - problems accessing resource

resourceName

public java.lang.String resourceName()
                              throws java.rmi.RemoteException

Retrieve the name of a resource.

Specified by:

resourceName in interface WfResource

Returns:

name of resource

Throws:

java.rmi.RemoteException - problems accessing resource

workItems

public java.util.Collection workItems()
                               throws java.rmi.RemoteException,
                                      java.lang.IllegalStateException

This method returns the WfAssignmentss associated with a resource.

Specified by:

workItems in interface WfResource

Returns:

the associated WfAssignmentss.

Throws:

java.rmi.RemoteException - if a system-level error occurs.

java.lang.IllegalStateException - if the resource has become invalid. This is actually a remapping of the NoSuchResourceException thrown by ResourceAssignmentService.workItems(). It must be remapped because this method's signature is specified by WfResource.workItems().

isMemberOfWorkItems

public boolean isMemberOfWorkItems(WfAssignment assignment)
                            throws java.rmi.RemoteException,
                                   java.lang.IllegalStateException

Checks if a given WfAssignment is associated with this resource.

Specified by:

isMemberOfWorkItems in interface WfResource

Parameters:

assignment - the assignment in question.

Returns:

true if the association exists.

Throws:

java.rmi.RemoteException - if a system-level error occurs. This is actually a remapping of the NoSuchResourceException thrown by ResourceAssignmentService.isMemberOfWorkItems(...). It must be remapped because this method's signature is specified by WfResource.isMemberOfWorkItems(...).

java.lang.IllegalStateException - if the resource has become invalid.

release

public void release(WfAssignment fromAssignment,
                    java.lang.String releaseInfo)
             throws java.rmi.RemoteException,
                    NotAssignedException

Signals to the resource that it is no longer needed for a specific assignment. The default implementation calls removeAssignment on the activity.

Specified by:

release in interface WfResource

Parameters:

fromAssignment - the specific assignment.

releaseInfo - specifies additional information on the reason for realizing the resource as input.

Throws:

NotAssignedException - if the resource is not associated with the given assignment.

java.rmi.RemoteException - if a system-level error occurs.
