Class PersistentGraphRepository

java.lang.Object
org.apache.jena.ontapi.impl.repositories.PersistentGraphRepository
All Implemented Interfaces:
GraphRepository
public class PersistentGraphRepository extends Object implements GraphRepository
A GraphRepository implementation that supports persistence via GraphMaker. Note that this repository does not permit modification of underlying storage (source). Removing graph from the source is not reflected by this repository, so it will still contain reference to the graph, even the graph is no longer available via GraphMaker.
