ReadOnlyGraph and ReadOnlyIndexableGraph wraps 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(), shutdown()
• IndexableGraph: dropIndex(), createIndex()
• Element: setProperty(), removeProperty()
• Index: put(), remove()
