Class AbstractLobType

Direct Known Subclasses:

BlobByteArrayType, BlobSerializableType, ClobStringType

public abstract class AbstractLobType

implements UserType

Abstract base class for Hibernate UserType implementations that map to LOBs. Retrieves the LobHandler to use from LocalSessionFactoryBean at config time.

Requires either active Spring transaction synchronization or a specified "jtaTransactionManager" on LocalSessionFactoryBean plus an active JTA transaction.

Offers template methods for getting and setting that pass in the LobHandler respectively LobCreator to use.
