de.danet.an.workflow.spis.ras.ActivityFinder

This interface defines facilities that map activity ids to {@link de.danet.an.workflow.omgcore.WfActivity WfActivity}objects. ActivityFinders are used (in combination with an identifier) to identify activities in calls to a {@link ResourceAssignmentService ResourceAssignmentService}. They are guaranteed to be serializable objects with properly implemented {@link java.lang.Object#equals equals} and {@link java.lang.Object#hashCode hashCode} methods.It is expected that resource assignment facilities keep a peristent, indexed record of ActivityFinders and store references to activities as tuples of a finder index and an activity identifier.

                prepStmt.setString (1, resource.resourceKey());
                rs = prepStmt.executeQuery();
                while (rs.next()){
                    long dbid = rs.getLong (1);
                    long idx = rs.getLong (2);
                    ActivityFinder finder = finderByIndex(idx);
                    String actKey = rs.getString(3);
                    try {
                        res.add (new Assignment (dbid, finder.find (actKey)));
                    } catch (NoSuchActivityException e) {
                        // race condition
                        logger.debug 
                            ("Found assignment to activity key " + actKey 
                             + " but not the activity: " + e.getMessage ());
