      • copyOf

        public static <K,​V> ImmutableBiMap<K,​V> copyOf​(java.util.Map<? extends K,​? extends V> map)
        Returns an immutable bimap containing the same entries as map. If map somehow contains entries with duplicate keys (for example, if it is a SortedMap whose comparator is not consistent with equals), the results of this method are undefined.

        Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.

        Throws:
        java.lang.IllegalArgumentException - if two keys have the same value
        java.lang.NullPointerException - if any key or value in map is null

        public static <K,​V> ImmutableBiMap<K,​V> copyOf​(java.lang.Iterable<? extends java.util.Map.Entry<? extends K,​? extends V>> entries)
        Returns an immutable bimap containing the given entries.
        Throws:
        java.lang.IllegalArgumentException - if two keys have the same value or two values have the same key
        java.lang.NullPointerException - if any key, value, or entry is null

      • inverse

        public abstract ImmutableBiMap<V,​K> inverse()
        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.

        The inverse of an ImmutableBiMap is another ImmutableBiMap.

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

        public ImmutableSet<V> values()
        Returns an immutable set of the values in this map. The values are in the same order as the parameters used to build this map.

        values in interface BiMap<K,​V>

        Unsupported operation.
        Guaranteed to throw an exception and leave the bimap unmodified.
        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 which was previously associated with the key, which may be null, or null if there was no previous entry
        Throws:
        java.lang.UnsupportedOperationException - always
