public abstract class AbstractLobType extends Object implements UserType
For writing LOBs, either an active Spring transaction synchronization or an active JTA transaction (with "jtaTransactionManager" specified on LocalSessionFactoryBean or a Hibernate TransactionManagerLookup configured through the corresponding Hibernate property) is required.
Offers template methods for setting parameters and getting result values, passing in the LobHandler or LobCreator to use.

AbstractLobType(LobHandler lobHandler,
TransactionManager jtaTransactionManager)
Constructor used for testing: takes an explicit LobHandler
and an explicit JTA TransactionManager (can be
null ). |
