ReadOnlyGraph and ReadOnlyIndexableGraph wrap any Graph or IndexableGraph, respectively. The purpose of a ReadOnlyGraph is to ensure that the graph is not mutated by a mutating method invocation. The following methods throw an UnsupportedOperationException:

• Graph: addVertex(), removeVertex(), addEdge(), removeEdge(), clear(), shutdown()
• IndexableGraph: dropIndex(), createManualIndex(), createAutomaticIndex()
• Element: setProperty(), removeProperty()
• Index: put(), remove()
