ContainerLocking2	A locking policy that implements container level locking with isolation degree 2.
ContainerLocking3	A locking policy that implements container level locking with isolation degree 3.
D_Xact	The D_Xact class provides diagnostic information about the Xact class.
EndXact	This operation indicates the End of a transaction.
EscalateContainerKey
GlobalXactId

LockCount
NoLocking	A locking policy that implements no locking.
RowLocking1	A locking policy that implements row level locking with isolation degree 1.
RowLocking2	A locking policy that implements row level locking with isolation degree 2.
RowLocking2nohold	A locking policy that implements row level locking with isolation degree 2, never holding read locks after they are granted.
RowLocking3	A locking policy that implements row level locking with isolation degree 3.
RowLocking3Escalate	A locking policy that implements row level locking with isolation degree 3.
RowLockingRR	A locking policy that implements row level locking with repeatable read isolation.
SavePoint
TransactionMapFactory	Helper class for TransactionTable which allows it to plug in a different java.util.Map implementation for the map that contains all the TransactionTableEntry instances in the transaction table.

TransactionTable.UpdateTransactionCounter	Visitor class that counts update transactions.
TransactionTableEntry	Transaction table entry is used to store all relevant information of a transaction into the transaction table for the use of checkpoint, recovery, Transaction management during Quiesce state, and for dumping transaction table.

XactContext	The context associated with the transaction.
XactFactory
XactId	Use this class for a short hand representation of the transaction.
