Method Detail

initialDataLoad

public DataIterator<Object> initialDataLoad()

Performs the initial load operation. Iterates over the #setInitialLoadEntries(String[]) initial load entries. If AbstractHibernateSpaceDataSource.getInitialLoadChunkSize() is set to -1, will use DefaultScrollableDataIterator for each entity. If AbstractHibernateSpaceDataSource.getInitialLoadChunkSize() is set to a non -1 value, will use the DefaultChunkScrollableDataIterator.

Overrides:

initialDataLoad in class SpaceDataSource

Returns:

A DataIterator instance which contains all data to be written to Space upon its initialization - null is treated as an empty iterator.

getDataIterator

public DataIterator<Object> getDataIterator(DataSourceQuery query)

Returns a DefaultListQueryDataIterator for the given sql query.

Overrides:

getDataIterator in class SpaceDataSource

Parameters:

query - The DataSourceQuery to get results for.

Returns:

A DataIterator instance contains results for the provided DataSourceQuery.
