      • containsKey

        public boolean containsKey​(java.lang.Object value)
        Specified by:
        containsKey in interface java.util.Map<V,​K>
        Overrides:
        containsKey in class java.util.AbstractMap<V,​K>
      • get

        public K get​(java.lang.Object value)
        Specified by:

        Overrides:
        get in class java.util.AbstractMap<V,​K>
      • put

        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 java.util.Map<V,​K>
        Overrides:
        put in class java.util.AbstractMap<V,​K>
      • forcePut

        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 which was previously associated with the key, which may be null, or null if there was no previous entry
      • remove

        public K remove​(java.lang.Object value)
        Specified by:
        remove in interface java.util.Map<V,​K>
        Overrides:
        remove in class java.util.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 java.util.Set<V> keySet()
        Specified by:
        keySet in interface java.util.Map<V,​K>
        Overrides:
        keySet in class java.util.AbstractMap<V,​K>
      • values

        public java.util.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 java.util.Map<V,​K>
        Overrides:
        values in class java.util.AbstractMap<V,​K>

        Specified by:
        forEach in interface java.util.Map<V,​K>
      • replaceAll

        public void replaceAll​(java.util.function.BiFunction<? super V,​? super K,​? extends K> function)
        Specified by:
