public class TransactionTable

extends java.lang.Object

TransactionTable provides a mapping between the calling thread and the Transaction it is currently using. One thread can be joined with one transaction at a certain point in time. But a thread can join with different transactions subsequently. This mapping from threads to Transactions is based on ODMG.
