Examples of com.arjuna.ats.jts.extensions.AtomicTransaction

com.arjuna.ats.jts.extensions.AtomicTransaction
Similar to CosTransactions::Current. However, this class does transaction scoping, so if an instance is garbage collected and the transaction is still running, it will be rolled back automatically. It also adds some convenience routines which Current does not do. @author Mark Little (mark_little@hp.com) @version $Id: AtomicTransaction.java 2342 2006-03-30 13:06:17Z $ @since JTS 1.0.
