Interface FilterObjectFactoryInterface

All Known Implementing Classes:

AdvancedBusinessModelFilterObjectFactory, AdvancedBusinessQueryFilterObjectFactory, BaseAdvancedFilterObjectFactory, BaseFilterObjectFactory, BusinessQueryFilterObjectFactory, InformationMapFilterObjectFactory

public interface FilterObjectFactoryInterface

The FilterObjectFactoryInterface defines the primary interface between native objects and the filter specific objects the filter model works with. All methods included in this class are in some way involved with converting objects back and forth between the filter model and a native model.
