All known Subclasses: com.sleepycat.je.txn.ThreadLocker, com.sleepycat.je.txn.BuddyLocker,
| BasicLocker | | public class BasicLocker extends Locker (Code) | | A concrete Locker that simply tracks locks and releases them when
operationEnd is called.
|
| Method Summary | |
| void | addLock(Long nodeId, LockType type, LockGrantType grantStatus)
Add a lock to set owned by this transaction. | | protected void | checkState(boolean ignoreCalledByAbort)
| | public LockStats | collectStats(LockStats stats)
| | public boolean | createdNode(long nodeId)
Always false for this txn. | | protected long | generateId(TxnManager txnManager)
BasicLockers always have a fixed id, because they are never used for
recovery. | | public long | getAbortLsn(long nodeId)
| | public long | getOwnerAbortLsn(long nodeId)
Get the abort LSN for this node in the txn that owns the lock on this
node. | | public Txn | getTxnLocker()
No transactional locker is available. | | public WriteLockInfo | getWriteLockInfo(long nodeId)
| | public Locker | getWriteOwnerLocker(long nodeId)
Get the txn that owns the lock on this node. | | public boolean | isReadCommittedIsolation()
Is never read-committed isolation. | | public boolean | isSerializableIsolation()
Is never serializable isolation. | | public boolean | isTransactional()
Is never transactional. | | LockResult | lockInternal(long nodeId, LockType lockType, boolean noWait, DatabaseImpl database)
| | public void | markDeleteAtTxnEnd(DatabaseImpl db, boolean deleteAtCommit)
| | void | moveWriteToReadLock(long nodeId, Lock lock)
A lock is being demoted. | | public Locker | newNonTxnLocker()
Creates a new instance of this txn for the same environment. | | public void | operationEnd()
Release locks at the end of the transaction. | | public void | operationEnd(boolean operationOK)
Release locks at the end of the transaction. | | public void | registerCursor(CursorImpl cursor)
This txn doesn't store cursors. | | public void | releaseNonTxnLocks()
Releases all locks, since all locks held by this locker are
non-transactional. | | void | removeLock(long nodeId)
Remove a lock from the set owned by this txn. | | public void | setHandleLockOwner(boolean operationOK, Database dbHandle, boolean dbIsClosing)
Transfer any MapLN locks to the db handle. | | public void | unRegisterCursor(CursorImpl cursor)
This txn doesn't store cursors. |
| generateId | | protected long generateId(TxnManager txnManager)(Code) | | BasicLockers always have a fixed id, because they are never used for
recovery.
|
| getOwnerAbortLsn | | public long getOwnerAbortLsn(long nodeId) throws DatabaseException(Code) | | Get the abort LSN for this node in the txn that owns the lock on this
node. Return null if there's no owning txn found.
|
| getTxnLocker | | public Txn getTxnLocker()(Code) | | No transactional locker is available.
|
| getWriteOwnerLocker | | public Locker getWriteOwnerLocker(long nodeId) throws DatabaseException(Code) | | Get the txn that owns the lock on this node. Return null if there's no
owning txn found.
|
| isReadCommittedIsolation | | public boolean isReadCommittedIsolation()(Code) | | Is never read-committed isolation.
|
| isSerializableIsolation | | public boolean isSerializableIsolation()(Code) | | Is never serializable isolation.
|
| isTransactional | | public boolean isTransactional()(Code) | | Is never transactional.
|
| moveWriteToReadLock | | void moveWriteToReadLock(long nodeId, Lock lock)(Code) | | A lock is being demoted. Move it from the write collection into the read
collection.
|
| 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.
|
| operationEnd | | public void operationEnd(boolean operationOK) throws DatabaseException(Code) | | Release locks at the end of the transaction.
|
| releaseNonTxnLocks | | public void releaseNonTxnLocks() throws DatabaseException(Code) | | Releases all locks, since all locks held by this locker are
non-transactional.
|
| removeLock | | void removeLock(long nodeId) throws DatabaseException(Code) | | Remove a lock from the set owned by this txn.
|
| setHandleLockOwner | | public void setHandleLockOwner(boolean operationOK, Database dbHandle, boolean dbIsClosing) throws DatabaseException(Code) | | Transfer any MapLN locks to the db handle.
