RTreeIterator

public RTreeIterator(RTree<T> tree,
                     double[] min,
                     double[] max)

Method Detail

createExactMatch

public static <T> RTreeIterator<T> createExactMatch(RTree<T> tree,
                                                    double[] min,
                                                    double[] max)

reset

public Index.BoxIterator<T> reset(double[] min,
                                  double[] max)

Description copied from interface: Index.QueryIterator

This method resets an iterator. The arguments determin new iterator properties: - For Extent iterators, see e.g. PointMap.iterator(), both arguments must be `null`. - For point query iterators, see e.g. PointMultimap.queryExactPoint(double[]), the first argument is the new query point and the second argument must be `null`. - For window queries, see e.g. PointMap.query(double[], double[]), the arguments are the min/max corners of the new query window.

Specified by:

reset in interface Index.QueryIterator<T>

Parameters:

min - point or `null`

max - point or `null`

Returns:

this iterator after reset.

hasNext

public boolean hasNext()

Specified by:
