Package org.apache.jackrabbit.core.state

Interface Summary

Cache	A Cache object A cache must call CacheManager.getInstance().add(this) to take part in the dynamic memory distribution.
CacheAccessListener	The cache access listener can be registered to a class.
ISMLocking	ISMLocking defines an interface for a locking strategy of an ItemStateManager.
ISMLocking.ReadLock
ISMLocking.WriteLock
ISMLockingFactory	Factory interface for creating ISMLocking instances.
ItemStateCache	An ItemStateCache maintains a cache of ItemState instances.
ItemStateCacheFactory	An item state cache factory to construct new item state caches.
ItemStateListener	The ItemStateListener interface allows an implementing object to be informed about changes on an ItemState.
ItemStateManager	The ItemStateManager interface provides methods for retrieving ItemState and NodeReferences instances by id.
ItemStateStore	ItemStateStore is similar to a typed Map: An ItemStateStore temporarily stores and retrieves ItemState instances using their ItemIds as key.
NodeStateListener	Extends the ItemStateListener allowing a client to be additionally informed about changes on a NodeState.
UpdatableItemStateManager	Identifies an ItemStateManager that allows updating items.

Class Summary

CacheManager	This class manages the size of the caches used in Jackrabbit.
CacheManager.CacheInfo	Internal copy of the cache information.
ChangeLog	Registers changes made to states and references and consolidates empty changes.
ChildNodeEntry	ChildNodeEntry specifies the name, index (in the case of same-name siblings) and the UUID of a child node entry.
DefaultISMLocking	DefaultISMLocking implements the default locking strategy using coarse grained locking on an ItemStateManager wide read-write lock.
FineGrainedISMLocking	FineGrainedISMLocking...
ItemState	ItemState represents the state of an Item.
ItemStateMap	A Map based ItemStateStore implementation.
ItemStateReferenceCache	ItemStateReferenceCache internally consists of 2 components: an ItemStateReferenceMap serving as the primary (or main) cache; it holds weak references to ItemState instances.
ItemStateReferenceMap	ItemStateReferenceMap is a specialized ItemStateMap that stores WEAK references to ItemState objects.
LocalItemStateManager	Local ItemStateManager that isolates changes to persistent states from other clients.
ManagedMLRUItemStateCacheFactory	This class constructs new MLRUItemStateCache.
MLRUItemStateCache	An ItemStateCache implementation that internally uses a LinkedMap to maintain a cache of ItemState objects.
NodeReferences	NodeReferences represents the references (i.e.
NodeState	NodeState represents the state of a Node.
PropertyState	PropertyState represents the state of a Property.
SessionItemStateManager	Item state manager that handles both transient and persistent items.
SharedItemStateManager	Shared ItemStateManager (SISM).
StateChangeDispatcher	Component that holds references to listeners interested in changes to item states and dispatches notifications.
XAItemStateManager	Extension to LocalItemStateManager that remembers changes on multiple save() requests and commits them only when an associated transaction is itself committed.

Exception Summary

ItemStateException	The ItemStateException ...
NoSuchItemStateException	The NoSuchItemStateException ...
StaleItemStateException	Signals that an item has been modified externally and that the item state representing it has thus become stale.
