Method Detail

getDataIterator

public DataIterator<Object> getDataIterator(DataSourceQuery query)

Description copied from class: DefaultHibernateSpaceDataSource

Returns a DefaultListQueryDataIterator for the given sql query.

Overrides:

getDataIterator in class DefaultHibernateSpaceDataSource

Parameters:

query - The DataSourceQuery to get results for.

Returns:

A DataIterator instance contains results for the provided DataSourceQuery.

getById

public Object getById(DataSourceIdQuery idQuery)

Description copied from class: SpaceDataSource

This method is invoked whenever the space needs to read an entry from the data source according to its Id.

The returned value can be either a POJO or a SpaceDocument instance.

The default implementation of this method is delegated to the SpaceDataSource.getDataIterator(DataSourceQuery) method so if the data source does not have an optimized way of reading an entity by its Id - the default implementation may suffice.

Overrides:

getById in class SpaceDataSource

Parameters:

idQuery - The DataSourceIdQuery to get a result for.

Returns:

A result from the SpaceDataSource which matches the provided DataSourceIdQuery.
