Package org.apache.tinkerpop.gremlin.tinkergraph.structure

Class TinkerGraphIterator<E>

java.lang.Object

org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerGraphIterator<E>

All Implemented Interfaces:

AutoCloseable, Iterator<E>, CloseableIterator<E>

public class TinkerGraphIterator<E>
extends Object
implements CloseableIterator<E>

Wrapper on top of Iterator representing a closable resource to the underlying storage. This class also serves as a reference on how the providers can maintain a counter of the underlying storage resources in their implementation. This counter in coordination with gremlin-test suite can be used to detect cases when the query processor does not gracefully release the underlying resources.
