Class GraphManager

java.lang.Object

org.apache.tinkerpop.gremlin.server.GraphManager

public final class GraphManager
extends Object

Holder for Graph and TraversalSource instances configured for the server to be passed to script engine bindings. The Graph instances are read from the Settings for Gremlin Server as defined in the configuration file. The TraversalSource instances are rebound to the GraphManager once initialization scripts construct them.
