Interface ItemSelectorCriterionHandler<T extends ItemSelectorCriterion>

All Known Implementing Classes:

BaseItemSelectorCriterionHandler

public interface ItemSelectorCriterionHandler<T extends ItemSelectorCriterion>

Provides an interface that returns the ItemSelectorView for a particular ItemSelectorCriterion. Every item selector criterion should have its own associated item selector criterion handler.

Implementations of this interface need to be registered as OSGi components using the service ItemSelectorCriterionHandler.

Unless an implementation needs custom logic to filter item selector views, it will simply need to extend BaseItemSelectorCriterionHandler and only implement the method getItemSelectorCriterionClass().
