[OJB-developers] Why use PersistenceBrokerImpl instead of PersistenceBroker in the constructor for StatementManager/connectionManager?

As I want to override the functins of PersistenceBrokerImpl to expose = more functions, I am wondering that in the constructor for: StatementManager.java ConnectionFactoryDefaultImpl.java ConnectionManager.java SequenceManager.java ... They all use the PersistenceBrokerImpl as a parameter in the = constructor, instead of using PersistenceBroker. I am wondering is there = specific reason to use impl instead of interface? Best regards, John W |
