      • containsValue

        public boolean containsValue​(char v)
        Description copied from interface: Object2CharMap
        Returns true if this map maps one or more keys to the specified value.

      • getOrDefault

        @Deprecated
        public java.lang.Character getOrDefault​(java.lang.Object key,
                                                java.lang.Character defaultValue)
        Deprecated.
        Description copied from interface: Object2CharMap
        Returns the value associated by this function to the specified key, or give the specified value if not present.

        This default implementation just delegates to the corresponding Map method.

        getOrDefault in interface Object2CharFunction<K>
        Specified by:
        getOrDefault in interface Object2CharMap<K>
        Parameters:
        key - the key.
        defaultValue - the default value to return if not present.
        Returns:
        the corresponding value, or defaultValue if no value was present for the given key.

        @Deprecated
        public boolean containsValue​(java.lang.Object ov)
        Deprecated.
        Please use the corresponding type-specific method instead.

        public void putAll​(java.util.Map<? extends K,​? extends java.lang.Character> m)

      • object2CharEntrySet

        public ObjectSet<Object2CharMap.Entry<K>> object2CharEntrySet()
        Description copied from interface: Object2CharMap
        Returns a type-specific set view of the mappings contained in this map.

        This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Map.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).

        Specified by:
        object2CharEntrySet in interface Object2CharMap<K>
        Returns:
        a type-specific set view of the mappings contained in this map.

      • keySet

        public ObjectSet<K> keySet()
        Description copied from interface: Object2CharMap
        Specified by:
        keySet in interface java.util.Map<K,​java.lang.Character>
        Specified by:
        keySet in interface Object2CharMap<K>
        Returns:
        a set view of the keys contained in this map.

      • values

        public CharCollection values()
        Description copied from interface: Object2CharMap
        Specified by:
        values in interface java.util.Map<K,​java.lang.Character>
        Specified by:
        values in interface Object2CharMap<K>
        Returns:
        a set view of the values contained in this map.
