Examples of net.timewalker.ffmq3.local.TransactionSet

net.timewalker.ffmq3.local.destination.LocalQueue

Set of {@link TransactionItem} objects. Used by the JMS {@link Session} implementation to keep track of the changes made in the current transaction.May be fully or partially cleared on commit/rollback operations. Thread-safe implementation.
