java.lang.Object

org.apache.tinkerpop.gremlin.util.iterator.StoreIteratorCounter

public class StoreIteratorCounter
extends Object

Utility class which can be used by providers to keep a count of the number of open iterators to the underlying storage. Please note that, by default, this does not maintain the count unless explicitly plugged-in by the provider implementation.

As an example on how to plugin-in the counter in the provider implementation check TinkerGraphIterator.
