Examples of ItemRegistry

org.openhab.core.items.ItemRegistry
The ItemRegistry is the central place, where items are kept in memory and their state is permanently tracked. So any code that requires the current state of items should use this service (instead of trying to keep their own local copy of the items). Items are registered by {@link ItemProvider}s, which can provision them from any source they like and also dynamically remove or add items. @author Kai Kreuzer @since 0.1.0
