Class HBasePersistenceBackend

java.lang.Object

fr.inria.atlanmod.neoemf.data.AbstractPersistenceBackend

fr.inria.atlanmod.neoemf.data.hbase.HBasePersistenceBackend

All Implemented Interfaces:

PersistenceBackend, Closeable, AutoCloseable

public class HBasePersistenceBackend
extends AbstractPersistenceBackend

Mock PersistenceBackend implementation for HBase to fit core architecture.

This class does not access HBase database, but is here to fit the requirement of the core architecture. For historical reasons the real access to the HBase Table is done in DirectWriteHBaseStore and ReadOnlyHBaseStore.

Moving HBase access to this class to fit NeoEMF back-end architecture is planned in a future release.
