Class JanusGraphManager

java.lang.Object

org.janusgraph.graphdb.management.JanusGraphManager

All Implemented Interfaces:

org.apache.tinkerpop.gremlin.server.GraphManager

public class JanusGraphManager
extends Object
implements org.apache.tinkerpop.gremlin.server.GraphManager

This class adheres to the TinkerPop graphManager specifications. It provides a coordinated mechanism by which to instantiate graph references on a given JanusGraph node and a graph reference tracker (or graph cache). Any graph created using the property \"graph.graphname\" and any graph defined at server start, i.e. in the server's YAML file, will go through this JanusGraphManager.
