Basically a Set of all transactions with add and remove methods and a latch around the set. Field Summary final static  long NULL_TXN_ID      Constructor Summary public   TxnManager(EnvironmentImpl env)      Method Summary public  Xid[] XARecover()      public  boolean areOtherSerializableTransactionsActive(Locker excludeLocker)      Returns whether there are any active serializable transactions, excluding the transaction given (if non-null). public  long getFirstActiveLsn()      Get the earliest LSN of all the active transactions, for checkpoint. public synchronized  long getLastTxnId()      Get the last used id, for checkpoint info. public  LockManager getLockManager()      Give transactions and environment access to lock manager. public  Transaction getTxnForThread()      Retrieve a Txn object for this Thread. public  Txn getTxnFromXid(Xid xid)      Retrieve a Txn object from an Xid. synchronized  long incTxnId()      Get the next transaction id to use. public  LockStats lockStat(StatsConfig config)      Collect lock related stats.  void registerTxn(Txn txn)      Called when txn is created. public  void registerXATxn(Xid xid, Txn txn, boolean isPrepare)      Called when txn is created. public synchronized  void setLastTxnId(long lastId)      Set the txn id sequence. public  void setTxnForThread(Transaction txn)      Called when txn is assoc'd with this thread. public  Txn txnBegin(Transaction parent, TransactionConfig txnConfig)      Create a new transaction. public  TransactionStats txnStat(StatsConfig config)      Collect transaction related stats.  void unRegisterTxn(Txn txn, boolean isCommit)      Called when txn ends.  void unRegisterXATxn(Xid xid, boolean isCommit)      Called when txn ends. public  Transaction unsetTxnForThread()      Called when txn is assoc'd with this thread. Field Detail NULL_TXN_ID final static long NULL_TXN_ID(Code) Constructor Detail TxnManager public TxnManager(EnvironmentImpl env) throws DatabaseException(Code) Method Detail XARecover public Xid[] XARecover() throws DatabaseException(Code) areOtherSerializableTransactionsActive public boolean areOtherSerializableTransactionsActive(Locker excludeLocker)(Code) Returns whether there are any active serializable transactions, excluding the transaction given (if non-null). This is intentionally returned without latching, since latching would not make the act of reading an integer more atomic than it already is. getFirstActiveLsn public long getFirstActiveLsn() throws DatabaseException(Code) Get the earliest LSN of all the active transactions, for checkpoint. getLastTxnId public synchronized long getLastTxnId()(Code) Get the last used id, for checkpoint info. getLockManager public LockManager getLockManager()(Code) Give transactions and environment access to lock manager. getTxnForThread public Transaction getTxnForThread() throws DatabaseException(Code) Retrieve a Txn object for this Thread. getTxnFromXid public Txn getTxnFromXid(Xid xid) throws DatabaseException(Code) Retrieve a Txn object from an Xid. incTxnId synchronized long incTxnId()(Code) Get the next transaction id to use. lockStat public LockStats lockStat(StatsConfig config) throws DatabaseException(Code) Collect lock related stats. registerTxn void registerTxn(Txn txn) throws DatabaseException(Code) Called when txn is created. registerXATxn public void registerXATxn(Xid xid, Txn txn, boolean isPrepare) throws DatabaseException(Code) Called when txn is created. setLastTxnId public synchronized void setLastTxnId(long lastId)(Code) Set the txn id sequence. setTxnForThread public void setTxnForThread(Transaction txn)(Code) Called when txn is assoc'd with this thread. txnBegin public Txn txnBegin(Transaction parent, TransactionConfig txnConfig) throws DatabaseException(Code) Create a new transaction. Parameters:   parent - for nested transactions, not yet supported Parameters:   txnConfig - specifies txn attributes the new txn txnStat public TransactionStats txnStat(StatsConfig config) throws DatabaseException(Code) Collect transaction related stats. unRegisterTxn void unRegisterTxn(Txn txn, boolean isCommit) throws DatabaseException(Code) Called when txn ends. unRegisterXATxn void unRegisterXATxn(Xid xid, boolean isCommit) throws DatabaseException(Code) Called when txn ends. unsetTxnForThread public Transaction unsetTxnForThread() throws DatabaseException(Code) Called when txn is assoc'd with this thread.
