Interface ResultIterator<I>

All Superinterfaces:
AutoCloseable, Iterator<I>, QueryResult
All Known Subinterfaces:
SqlResultIterator
All Known Implementing Classes:
DataResultIterator, DynamicResultIterator, ItemResultIterator, PlotServlet.CFResultIterator, ReporterScoreResultIterator
public interface ResultIterator<I>
extends QueryResult, Iterator<I>, AutoCloseable
Return the result of a query as an iterator. An iterator doesn't load the entire dataset into memory at once, it waits until the client application request the next row. This interface is useful for all types of queries and mostly for queries that might return a large number of items.

Implementors should not allow modifications to the iterator, ie. it is not allowed to call the Iterator.remove() method.
