- entityManager
- EntityManager holding the Entities
- filter
- A predicate returning true if the tested entity belongs in the list
- filterProperties
-               The watched properties. If supplied, changes to values in the watched properties trigger filtering.               If null, any changes to Entities of this type will trigger filtering.
