List of descendingMap() Examples

Examples of descendingMap()

edu.stanford.ppl.concurrent.SnapTreeMap.descendingMap()
java.util.NavigableMap.descendingMap()
Returns a reverse order view of the mappings contained in this map. The descending map is backed by this map, so changes to the map are reflected in the descending map, and vice-versa. If either map is modified while an iteration over a collection view of either map is in progress (except through the iterator's own {@code remove}operation), the results of the iteration are undefined.
The returned map has an ordering equivalent to {@link Collections#reverseOrder(Comparator) Collections.reverseOrder}(comparator()). The expression {@code m.descendingMap().descendingMap()} returns aview of {@code m} essentially equivalent to {@code m}. @return a reverse order view of this map
