Examples of org.apache.jackrabbit.core.ItemManager

org.apache.jackrabbit.core.ItemManager
There's one ItemManager instance per Session instance. It is the factory for Node and Property instances.
The ItemManager's responsabilities are:
- providing access to Item instances by ItemId whereas Node and Item are only providing relative access.
- returning the instance of an existing Node or Property, given its absolute path.
- creating the per-session instance of a Node or Property that doesn't exist yet and needs to be created first.
- guaranteeing that there aren't multiple instances representing the same Node or Property associated with the same Session instance.
- maintaining a cache of the item instances it created.
- respecting access rights of associated Session in all methods.
If the parent Session is an XASession, there is one ItemManager instance per started global transaction.
