| ReadCommittedLocker | | public class ReadCommittedLocker extends BuddyLocker (Code) | | Extends BuddyLocker to acquire write locks using the buddy locker (the
transaction locker). This is used for ReadCommitted (Degree 2) isolation.
|
| ReadCommittedLocker | | public ReadCommittedLocker(EnvironmentImpl env, Locker buddy) throws DatabaseException(Code) | | Creates a ReadCommittedLocker.
Parameters:
buddy - is a transactional locker that will be used for acquiringwrite locks. |
| addDeleteInfo | | public void addDeleteInfo(BIN bin, Key deletedKey) throws DatabaseException(Code) | | Forwards this method to the transactional buddy. The buddy handles
write locks and therefore handles delete information.
|
| createdNode | | public boolean createdNode(long nodeId) throws DatabaseException(Code) | | Forwards this method to the transactional buddy. Since the buddy
handles write locks, it knows whether this transaction created the node.
|
| getAbortLsn | | public long getAbortLsn(long nodeId) throws DatabaseException(Code) | | Forwards this method to the transactional buddy. The buddy handles
write locks and therefore handles abort information.
|
| isReadCommittedIsolation | | public boolean isReadCommittedIsolation()(Code) | | Is always read-committed isolation.
|
| isTransactional | | public boolean isTransactional()(Code) | | Is always transactional because the buddy locker is transactional.
|
| newNonTxnLocker | | public Locker newNonTxnLocker() throws DatabaseException(Code) | | Creates a new instance of this txn for the same environment. No
transactional locks are held by this object, so no locks are retained.
newNonTxnLocker is also called for the BuddyLocker.
|
| registerCursor | | public void registerCursor(CursorImpl cursor) throws DatabaseException(Code) | | Forwards this method to the transactional buddy. The buddy Txn tracks
cursors.
|
| releaseLock | | public void releaseLock(long nodeId) throws DatabaseException(Code) | | Releases the lock from this locker, or if not owned by this locker then
releases it from the buddy locker.
|
| unRegisterCursor | | public void unRegisterCursor(CursorImpl cursor) throws DatabaseException(Code) | | Forwards this method to the transactional buddy. The buddy Txn tracks
cursors.
