Examples of org.neo4j.graphdb.index.IndexManager.forNodes()

org.neo4j.graphdb.index.IndexManager.forNodes()
Returns an {@link Index} for {@link Node}s with the name {@code indexName}. If such an index doesn't exist it will be created with default configuration. Indexes created with {@link #forNodes(String,Map)} can be returned by thismethod also, so that you don't have to supply and match its configuration for consecutive accesses. This is the prefered way of accessing indexes, whether they were created with {@link #forNodes(String)} or {@link #forNodes(String,Map)}. @param indexName the name of the node index. @return the {@link Index} corresponding to the {@code indexName}.
