Interface IGenericDaoTransaction

public interface IGenericDaoTransaction

* NOTE: Experimental!!

This interface represents a transaction that is executed inside one Mr. Persisters dao instances (fx. by calling IGenericDao.executeTransaction()). A dao command may contain multiple actions, for instance reading and updating various objects in the database.

The advantage of dao commands is typically that some of the standard JDBC work can be taken over by the dao instance. For instance committing or rolling back the transaction and closing the connection after the transaction is executed.
