## org.springframework.orm.hibernate.support
Class BlobByteArrayType

    java.lang.Object
      org.springframework.orm.hibernate.support.AbstractLobType
          org.springframework.orm.hibernate.support.BlobByteArrayType

All Implemented Interfaces:
  net.sf.hibernate.UserType

    public class BlobByteArrayType

extends AbstractLobType

Hibernate UserType implementation for byte arrays that get mapped to BLOBs. Retrieves the LobHandler to use from LocalSessionFactoryBean at config time.

Can also be defined in generic Hibernate mappings, as DefaultLobCreator will work with most JDBC-compliant database drivers. In this case, the field type does not have to be BLOB: For databases like MySQL and MS SQL Server, any large enough binary type will work.

  1.1

Constructor Summary
`` | `BlobByteArrayType()` Constructor used by Hibernate: fetches config-time LobHandler and config-time JTA TransactionManager from LocalSessionFactoryBean.
`protected` | `BlobByteArrayType(LobHandler lobHandler, TransactionManager jtaTransactionManager)` Constructor used for testing: takes an explicit LobHandler and an explicit JTA TransactionManager (can be `null`).

Method Summary

`boolean` | `equals(Object x, Object y)` This implementation delegates to the Hibernate EqualsHelper.
`boolean` | `isMutable()` This implementation returns false.
`protected Object` | `nullSafeGetInternal(ResultSet rs, int index, LobHandler lobHandler)` Template method to extract a value from the given result set.
`protected void` | `nullSafeSetInternal(PreparedStatement ps, int index, Object value, LobCreator lobCreator)` Template method to set the given parameter value on the given statement.
