      • decorate

        public static OrderedMap decorate​(OrderedMap map)
        Deprecated.
        Factory method to create an unmodifiable sorted map.

        map - the map to decorate, must not be null
        Throws:

      • mapIterator

        public MapIterator mapIterator()
        Deprecated.
        Description copied from interface: IterableMap
        Obtains a MapIterator over the map.

        A map iterator is an efficient way of iterating over maps. There is no need to access the entry set or cast to Map Entry objects.

         IterableMap map = new HashedMap();
         MapIterator it = map.mapIterator();
         while (it.hasNext()) {
           Object key = it.next();
           Object value = it.getValue();
           it.setValue("newValue");
         }
         
        Specified by:
        mapIterator in interface IterableMap
        Overrides:
        mapIterator in class AbstractOrderedMapDecorator
        Returns:
        a map iterator
      • orderedMapIterator

        public OrderedMapIterator orderedMapIterator()
        Deprecated.
        Description copied from interface: OrderedMap
        Obtains an OrderedMapIterator over the map.

        A ordered map iterator is an efficient way of iterating over maps in both directions.

         BidiMap map = new TreeBidiMap();
         MapIterator it = map.mapIterator();
         while (it.hasNext()) {
           Object key = it.next();
           Object value = it.getValue();
           it.setValue("newValue");
           Object previousKey = it.previous();
         }
