java.lang.Object org.apache.jackrabbit.core.state.LocalItemStateManager org.apache.jackrabbit.core.state.XAItemStateManager
Extension to LocalItemStateManager
that remembers changes on
multiple save() requests and commits them only when an associated transaction
is itself committed.

Constructor Summary | |
XAItemStateManager(SharedItemStateManager sharedStateMgr,
EventStateCollectionFactory factory)
Creates a new instance of this class. |
|
XAItemStateManager(SharedItemStateManager sharedStateMgr,
EventStateCollectionFactory factory,
String attributeName)
Creates a new instance of this class with a custom attribute name. |
Method Summary | |
void |
afterOperation(TransactionContext tx)
Invoked after one of the InternalXAResource.prepare(org.apache.jackrabbit.core.TransactionContext) , InternalXAResource.commit(org.apache.jackrabbit.core.TransactionContext) or
InternalXAResource.rollback(org.apache.jackrabbit.core.TransactionContext) method has been called. |
void |
associate(TransactionContext tx)
Associate this resource with a transaction. All further operations on the object should be interpreted as part of this transaction and changes recorded in some attribute of the transaction context. |
void |
beforeOperation(TransactionContext tx)
Invoked before one of the InternalXAResource.prepare(org.apache.jackrabbit.core.TransactionContext) , InternalXAResource.commit(org.apache.jackrabbit.core.TransactionContext) or
InternalXAResource.rollback(org.apache.jackrabbit.core.TransactionContext) method is called. |
void |
commit(TransactionContext tx)
Commit transaction. The transaction is identified by a transaction context. If the method throws, other resources get their changes rolled back. |
ChangeLog |
getChangeLog()
Returns the current change log. |
ItemState |
getItemState(ItemId id)
Return an item state, given its item id. If this state manager is committing changes, this method first checks the commitLog ThreadLocal. |
NodeReferences |
getNodeReferences(NodeReferencesId id)
Return a node references object, given its target id If this state manager is committing changes, this method first checks the commitLog ThreadLocal. |
boolean |
hasItemState(ItemId id)
Return a flag indicating whether an item state for a given item id exists. If this state manager is committing changes, this method first checks the commitLog ThreadLocal. |
boolean |
hasNodeReferences(NodeReferencesId id)
Return a flag indicating whether a node references object for a given target id exists. If this state manager is committing changes, this method first checks the commitLog ThreadLocal. |
void |
prepare(TransactionContext tx)
Prepare transaction. The transaction is identified by a transaction context. |
void |
rollback(TransactionContext tx)
Rollback transaction. The transaction is identified by a transaction context. |
void |
setVirtualProvider(VirtualItemStateProvider virtualProvider)
Set optional virtual item state provider. |
protected void |
update(ChangeLog changeLog)
End an update operation. Fetch the states and references from the parent (shared) item manager, reconnect them to the items collected in our (local) change log and overwrite the shared items with our copies. If associated with a transaction, simply merge the changes given to the ones already known (removing items that were first added and then again deleted). |
