Implement the IObjectSelector interface to provide client-side filtering of objects through the Scheduler.CountObjectsWhere and Scheduler.GetObjectsOfClassWhere method.

To create an object selector for use with the Scheduler.CountObjectsWhere and Scheduler.GetObjectsOfClassWhere method, you must create an object that implements IObjectSelector. 

When you call GetObjectsOfClassWhere, you pass it an IObjectSelector interface. The Scheduler object then calls the selector's SelectObject method for each object of the specified class, and returns all objects for which SelectObject returns True.
