java.lang.Objectorg.apache.jackrabbit.core.ItemManager
public class ItemManager
There's one ItemManager
instance per Session
instance. It is the factory for Node
and Property
instances.
ItemManager
's responsibilities are:
Item
instances by ItemId
whereas Node
and Item
are only providing relative access.
Node
or Property
,
given its absolute path.
Node
or Property
that doesn't exist yet and needs to be created first.
Node
or Property
associated with the same
Session
instance.
Session
in all methods.
Session
is an XASession
, there is
one ItemManager
instance per started global transaction.

ItemImpl |
getItem(ItemId id)
|
ItemImpl |
getItem(Path path)
Deprecated. As of JSR 283, a Path doesn't anymore uniquely
identify an Item , therefore getNode(Path) and
getProperty(Path) should be used instead. |
NodeImpl |
getNode(NodeId id,
NodeId parentId)
Returns a node with a given id and parent id. |
NodeImpl |
getNode(Path path)
|
PropertyImpl |
getProperty(Path path)
|
void |
itemDestroyed(ItemId id,
ItemData data)
|
boolean |
itemExists(ItemId id)
Checks if the item with the given id exists. |
boolean |
itemExists(Path path)
Deprecated. As of JSR 283, a Path doesn't anymore uniquely
identify an Item , therefore nodeExists(Path) and
propertyExists(Path) should be used instead. |
void |
itemInvalidated(ItemId id,
ItemData data)
|
boolean |
nodeExists(Path path)
Checks whether a node exists at the specified path. |
boolean |
propertyExists(Path path)
Checks whether a property exists at the specified path. |
void |
stateCreated(ItemState created)
Called when an ItemState has successfully
been created (i.e. its underlying persistent state was created). |
void |
stateDestroyed(ItemState destroyed)
Called when an ItemState has successfully been
removed (i.e. its underlying persistent state has been destroyed). |
void |
stateDiscarded(ItemState discarded)
Called when an ItemState has been discarded (i.e. it has
been rendered 'invalid'). |
void |
stateModified(ItemState modified)
Called when an ItemState has successfully
been modified (i.e. its underlying persistent state has changed). |
