Transaction¶

public interface Transaction¶

The Transaction interface allows operations to be performed against the transaction in the target Transaction object. A Transaction object is created by a corresponding DAO factory. Before any transaction starts, the Transaction object should be notified by the invocation of its begin() method. When the transaction is finished, either commit() or rollback should be invoked and the resources it acquired should be released accordingly.
