```
public boolean workItemInDue(ItemCollection doc,
                             ItemCollection docActivity)
```
    This method checks if a workitem (doc) is in due. There are 4 different cases which will be compared: The case is determined by the keyScheduledBaseObject of the activity entity Basis : keyScheduledBaseObject "last process"=1, "last Modification"=2 "Creation"=3 "Field"=4 The logic is not the best one but it works. So we are open for any kind of improvements
    
    Returns:
    
    true if workitem is is due
  - addWorkDays
```
public Calendar addWorkDays(Calendar baseDate,
                            int days)
```
    This method adds workdays (MONDAY - FRIDAY) to a given calendar object. If the number of days is negative than this method subtracts the working days from the calendar object.
    
    Parameters:
    
    cal -
    
    days -
    
    Returns:
    
    new calendar instance
  - run
```
public ItemCollection run(ItemCollection configItemCollection)
                   throws SchedulerException
```
    This method process scheduled workitems. The method updates the property 'datLastRun' Because of bug: https://java.net/jira/browse/GLASSFISH-20673 we check the imixsDayOfWeek
    
    Specified by:
    
    run in interface Scheduler
    
    Parameters:

                                                  throws ModelException
```
    This method collects all scheduled workflow events. A scheduled workflow event is identified by the attribute keyScheduledActivity="1" The method goes through the latest or a specific Model Version
    
    Throws:
    
    ModelException
  - processWorkListByEvent
```
protected void processWorkListByEvent(ItemCollection event,
                                      ItemCollection configItemCollection)

                                      QueryException
```
    This method processes all workitems for a specific scheduled event element of a workflow model. A scheduled event element can define a selector (txtscheduledview). If no selector is defined, the default selector is used:
    ($taskid:"[TASKID]" AND $modelversion:"[MODELVERSION]")
    
    Parameters:
    
    event - - a event model element
    
    Throws:
    
    ModelException
