Examples of it.unimi.dsi.mg4j.search.DocumentIterator.intervalIterator()

it.unimi.dsi.mg4j.search.DocumentIterator.intervalIterator()
Returns the interval iterator of this document iterator for single-index queries.
This is a commodity method that can be used only for queries built over a single index. @return an interval iterator. @see #intervalIterator(Index) @throws IllegalStateException if this document iterator is not built on a single index.
