Constructor Detail

DefaultHibernateExternalDataSource

public DefaultHibernateExternalDataSource()
Deprecated. 
Method Detail

setUseMerge

public void setUseMerge(boolean useMerge)
Deprecated. 
If set to true, will use Hibernate merge to perform the create/update, and will merge before calling delete. This might be required for complex mappings (depends on Hibernate) at the expense of slower performance. Defaults to false.


setDeleteById

public void setDeleteById(boolean deleteById)
Deprecated. 
If set to true the object will be deleted using only its id. If set to false the object will be deleted using the whole object. Defaults to true.

Parameters:
deleteById -

executeBulk

public void executeBulk(List<BulkItem> bulkItems)
                 throws DataSourceException
Deprecated. 
Perform the given bulk changes using Hibernate Session.

Note, this implementation relies on Hibernate NonUniqueObjectException in case the entity is already associated with the given session, and in such a case, will result in performing merge operation (which is more expensive).

Specified by:
executeBulk in interface BulkDataPersister
Parameters:
bulkItems - list of data object and the operation to apply on that object
Throws:
DataSourceException - when the data store fails to persist the given list of objects

iterator

public DataIterator iterator(SQLQuery sqlQuery)
                      throws DataSourceException
Deprecated. 
Returns a DefaultListQueryDataIterator for the given sql query.

Specified by:
iterator in interface SQLDataProvider
Returns:
a DataIterator or null if no data was found that match the given template
Throws:
DataSourceException

initialLoad

public DataIterator initialLoad()
                         throws DataSourceException
Deprecated. 
Performs the initial load operation. Iterates over the AbstractHibernateExternalDataSource.setInitialLoadEntries(String[]) initial load entries. If AbstractHibernateExternalDataSource.getInitialLoadChunkSize() is set to -1, will use DefaultScrollableDataIterator for each entity. If AbstractHibernateExternalDataSource.getInitialLoadChunkSize() is set to a non -1 value, will use the DefaultChunkScrollableDataIterator.

Specified by:
initialLoad in interface ManagedDataSource
Returns:
a DataIterator or null if no data should be loaded into space
Throws:
DataSourceException

getIdentifier

protected Serializable getIdentifier(Object o)
Deprecated. 
Extracts and returns the hibernate object identifier

Parameters:
o -
Returns:
serializable
