createInitialLoadIterator

protected DataIterator createInitialLoadIterator(DataIterator[] iterators)

A helper method that creates the initial load iterator using the ConcurrentMultiDataIterator with the provided #setInitialLoadThreadPoolSize(int) thread pool size.

isManagedEntry

protected boolean isManagedEntry(String entityName)

Returns if the given entity name is part of the getManagedEntries() list.

supportsInheritance

public boolean supportsInheritance()

Description copied from class: SpaceDataSource

Determines whether this implementation supports types inheritance.

If types inheritance is not supported - SpaceDataSource.getDataIterator(DataSourceQuery) will be invoked for each derived type of the query's data type. Otherwise a single SpaceDataSource.getDataIterator(DataSourceQuery) invocation will be made for the query.

Overrides:

supportsInheritance in class SpaceDataSource

Returns:

true if this SpaceDataSource implementation supports types inheritance, otherwise false.

getManagedEntries

public Iterable<String> getManagedEntries()

Specified by:
