Examples of OGraphDatabase

com.orientechnologies.orient.core.db.graph.OGraphDatabase
Super light GraphDB implementation on top of the underlying Document. The generated vertexes and edges are compatible with those of ODatabaseGraphTx and TinkerPop Blueprints implementation. This class is the fastest and lightest but you have ODocument instances and not regular ad-hoc POJO as for other implementations. You could use this one for bulk operations and the others for regular graph access. @author Luca Garulli
