        public static <K,​V> SortedBidiMap<K,​V> unmodifiableSortedBidiMap​(SortedBidiMap<K,​? extends V> map)
        Factory method to create an unmodifiable map.

        If the map passed in is already unmodifiable, it is returned.

        Type Parameters:
        K - the key type
        V - the value type
        Parameters:
        map - the map to decorate, must not be null
        Returns:
        an unmodifiable SortedBidiMap
        Throws:
        java.lang.NullPointerException - if map is null
        Since:

      • values

        public java.util.Set<V> values()
        Description copied from interface: BidiMap
        Returns a Set view of the values contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Collection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
        Specified by:
        values in interface BidiMap<K,​V>
        Specified by:
        values in interface Get<K,​V>
        Specified by:
        values in interface java.util.Map<K,​V>
        Specified by:
        values in interface java.util.SortedMap<K,​V>
        Overrides:
        values in class AbstractBidiMapDecorator<K,​V>
        Returns:
        a set view of the values contained in this map

        Map.values()
      • removeValue

        public K removeValue​(java.lang.Object value)
        Description copied from interface: BidiMap
        Removes the key-value pair that is currently mapped to the specified value (optional operation).

        If the value is not contained in the map, null is returned.

        Implementations should seek to make this method perform equally as well as remove(Object).

        Specified by:
        removeValue in interface BidiMap<K,​V>
        Overrides:
        removeValue in class AbstractBidiMapDecorator<K,​V>
        Parameters:
        value - the value to find the key-value pair for
        Returns:
        the key that was removed, null if nothing removed
      • mapIterator

        public OrderedMapIterator<K,​V> mapIterator()
        Description copied from class: AbstractIterableMap
        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 use Map Entry objects.

         IterableMap map = new HashedMap();
         MapIterator it = map.mapIterator();
         while (it.hasNext()) {
           String key = it.next();
           Integer value = it.getValue();
           it.setValue(value + 1);
         }
         
        Specified by:
        mapIterator in interface IterableGet<K,​V>
        Specified by:
        mapIterator in interface OrderedMap<K,​V>
        Overrides:
        mapIterator in class AbstractOrderedBidiMapDecorator<K,​V>
        Returns:
        a map iterator
      • inverseBidiMap

        public SortedBidiMap<V,​K> inverseBidiMap()
        Description copied from interface: BidiMap
        Gets a view of this map where the keys and values are reversed.

        Changes to one map will be visible in the other and vice versa. This enables both directions of the map to be accessed as a Map.

        Implementations should seek to avoid creating a new object every time this method is called. See AbstractMap.values() etc. Calling this method on the inverse map should return the original.

        inverseBidiMap in interface BidiMap<K,​V>
        Specified by:
        inverseBidiMap in interface OrderedBidiMap<K,​V>
        Specified by:

        Overrides:
        inverseBidiMap in class AbstractSortedBidiMapDecorator<K,​V>
        Returns:
        an inverted bidirectional map
