GraphFactory Settings

If using GraphFactory to instantiate a Neo4jGraph, the following properties will apply:

key description
blueprints.graph com.tinkerpop.blueprints.impls.neo4j.Neo4jGraph
blueprints.neo4j.directory The directory of the Neo4jGraph instance.
blueprints.neo4j.conf.* The prefix to use for any Neo4j specific settings (e.g. blueprints.neo4j.conf.string_block_size).

Neo4jGraph Feature List

Neo Technology are the developers of the Neo4j graph database. Neo4j natively supports the property graph data model. Note that Neo4j requires that the value objects in the property map of an element be Java primitives, java.lang.String values, or arrays of primitives and java.lang.String values. Neo4jElement will also accept a Collection of like primitives or java.lang.String values and will convert those to the appropriate array type for storage in Neo4j.

Indices with Neo4jGraph

It is possible to parameterize the indices created through Blueprints. Learn more about the types of indices supported by Neo4j at this location.

Index<Vertex> index = graph.createIndex("myIdx", Vertex.class, new Parameter("analyzer", LowerCaseKeywordAnalyzer.class.getName()));
Vertex a = graph.addVertex(null);
a.setProperty("name", "marko");
index.put("name", "marko", a);
Iterator itty = graph.getIndex("myIdx", Vertex.class).query("name", "MaRkO").iterator();
assertEquals(itty.next(), a);
