Class LuceneDataSource

java.lang.Object

org.neo4j.kernel.impl.transaction.xaframework.XaDataSource

org.neo4j.kernel.impl.transaction.xaframework.LogBackedXaDataSource

org.neo4j.index.impl.lucene.LuceneDataSource

All Implemented Interfaces:

org.neo4j.kernel.lifecycle.Lifecycle

public class LuceneDataSource
extends org.neo4j.kernel.impl.transaction.xaframework.LogBackedXaDataSource

An XaDataSource optimized for the LuceneIndexImplementation. This class is public because the XA framework requires it.
