Method Detail

setInitalLoadThreadPoolSize

public void setInitalLoadThreadPoolSize(int initalLoadThreadPoolSize)

getDataSource

protected SpaceDataSource getDataSource(String entry)

initialDataLoad

public DataIterator<Object> initialDataLoad()

Iterates through all the given data sources and assembles their respective DataIterators from SpaceDataSource.initialDataLoad(). Constructs a ConcurrentMultiDataIterator on top of them.

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.

initialMetadataLoad

public DataIterator<SpaceTypeDescriptor> initialMetadataLoad()

Iterates through all the given data sources and assembles their respective DataIterators from SpaceDataSource.initialMetadataLoad(). Constructs a SerialMultiDataIterator on top of them.

Overrides:

initialMetadataLoad in class SpaceDataSource

Returns:

A DataIterator instance which contains all SpaceTypeDescriptor instances to be introduced to the Space upon its initialization - null is treated as an empty iterator.

getDataIterator

public DataIterator<Object> getDataIterator(DataSourceQuery query)

Delegates the query to the corresponding data source

Overrides:

getDataIterator in class SpaceDataSource

Parameters:

query - The DataSourceQuery to get results for.

Returns:

A DataIterator instance contains results for the provided DataSourceQuery.

getById

public Object getById(DataSourceIdQuery idQuery)

Delegates the query to the corresponding data source

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.

getDataIteratorByIds

public DataIterator<Object> getDataIteratorByIds(DataSourceIdsQuery idsQuery)

Delegates the query to the corresponding data source

Overrides:

getDataIteratorByIds in class SpaceDataSource

Parameters:

idsQuery - The DataSourceIdsQuery to get a result for.

Returns:

A DataIterator instance contains results for the provided DataSourceIdsQuery.
