  • Method Details

    • delegate

      protected Map<K,V> delegate()
      Description copied from class: ForwardingObject
      Returns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such as ForwardingSet.delegate(). Concrete subclasses override this method to supply the instance being decorated.
      Specified by:
      delegate in class ForwardingMap<K,V>
    • forcePut

      @CheckForNull public V forcePut(K key, V value)
      Description copied from interface: BiMap
      An alternate form of put that silently removes any existing entry with the value value before proceeding with the BiMap.put(K, V) operation. If the bimap previously contained the provided key-value mapping, this method has no effect.

      Note that a successful call to this method could cause the size of the bimap to increase by one, stay the same, or even decrease by one.

      Warning: If an existing entry with this value is removed, the key for that entry is discarded and not returned.

      Specified by:
      forcePut in interface BiMap<K,V>
      Parameters:
      key - the key with which the specified value is to be associated
      value - the value to be associated with the specified key
      Returns:
      the value that was previously associated with the key, or null if there was no previous entry. (If the bimap contains null values, then forcePut, like put, returns null both if the key is absent and if it is present with a null value.)
    • replaceAll

      public void replaceAll(BiFunction<? super K,? super V,? extends V> function)
      Specified by:
      replaceAll in interface Map<K,V>
    • putIfAbsent

      @CheckForNull public V putIfAbsent(K key, V value)
      Specified by:
      putIfAbsent in interface Map<K,V>
    • remove

      public boolean remove(Object key, Object value)
      Specified by:
      remove in interface Map<K,V>
    • replace

      public boolean replace(K key, V oldValue, V newValue)
      Specified by:
      replace in interface Map<K,V>
    • replace

      @CheckForNull public V replace(K key, V value)
      Specified by:
      replace in interface Map<K,V>
    • computeIfAbsent

      public V computeIfAbsent(K key, Function<? super K,? extends V> mappingFunction)
      Specified by:
      computeIfAbsent in interface Map<K,V>
    • computeIfPresent

      @CheckForNull public V computeIfPresent(K key, BiFunction<? super K,? super V,? extends V> remappingFunction)
      Specified by:
      computeIfPresent in interface Map<K,V>
    • compute

      @CheckForNull public V compute(K key, BiFunction<? super K,? super V,? extends V> remappingFunction)
      Specified by:
      compute in interface Map<K,V>
    • merge

      @CheckForNull public V merge(K key, V value, BiFunction<? super V,? super V,? extends V> function)
      Specified by:
      merge in interface Map<K,V>
    • inverse

      public BiMap<V,K> inverse()
      Description copied from interface: BiMap
      Returns the inverse view of this bimap, which maps each of this bimap's values to its associated key. The two bimaps are backed by the same data; any changes to one will appear in the other.

      Note:There is no guaranteed correspondence between the iteration order of a bimap and that of its inverse.

      Specified by:
      inverse in interface BiMap<K,V>
      Returns:
      the inverse view of this bimap
    • values

      public Set<V> values()
      Description copied from interface: BiMap

      Because a bimap has unique values, this method returns a Set, instead of the Collection specified in the Map interface.

      Specified by:
      values in interface BiMap<K,V>
      Specified by:
      values in interface Map<K,V>
      Overrides:
      values in class ForwardingMap<K,V>
