    • size

      public int size()
      Specified by:

    • clear

      public void clear()
      Specified by:
      clear in interface Map<V,K>
      Overrides:
      clear in class Maps.IteratorBasedAbstractMap<V,K>
    • containsKey

      public boolean containsKey(@CheckForNull Object value)
      Specified by:
      containsKey in interface Map<V,K>
      Overrides:
      containsKey in class AbstractMap<V,K>
    • get

      @CheckForNull public K get(@CheckForNull Object value)
      Specified by:
      get in interface Map<V,K>
      Overrides:
      get in class AbstractMap<V,K>
    • put

      @CheckForNull public K put(V value, K key)
      Description copied from interface: BiMap
      Specified by:
      put in interface BiMap<V,K>
      Specified by:
      put in interface Map<V,K>
      Overrides:
      put in class AbstractMap<V,K>
    • forcePut

      @CheckForNull public K forcePut(V value, K key)
      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<V,K>
      Parameters:
      value - the key with which the specified value is to be associated
      key - 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.)
    • remove

      @CheckForNull public K remove(@CheckForNull Object value)
      Specified by:
      remove in interface Map<V,K>
      Overrides:
      remove in class AbstractMap<V,K>
    • inverse

      public BiMap<K,V> 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<V,K>
      Returns:
      the inverse view of this bimap
    • keySet

      public Set<V> keySet()
      Specified by:
      keySet in interface Map<V,K>
      Overrides:
      keySet in class AbstractMap<V,K>
    • values

      public Set<K> 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<V,K>
      Specified by:
      values in interface Map<V,K>
      Overrides:
      values in class AbstractMap<V,K>
    • entryIterator

      Iterator<Map.Entry<V,K>> entryIterator()
      Specified by:
      entryIterator in class Maps.IteratorBasedAbstractMap<V,K>
    • forEach

      public void forEach(BiConsumer<? super V,? super K> action)
      Specified by:
      forEach in interface Map<V,K>
    • replaceAll

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

      Object writeReplace()
    • readObject

      private void readObject(ObjectInputStream in) throws InvalidObjectException
      Throws:
      InvalidObjectException
