Class Char2ReferenceMaps.EmptyMap<V>

    • Method Detail

      • containsValue

        public boolean containsValue​(java.lang.Object v)
        Specified by:
        containsValue in interface java.util.Map<java.lang.Character,​V>
      • getOrDefault

        @Deprecated
        public V getOrDefault​(java.lang.Object key,
                              V defaultValue)
        Deprecated.
        Description copied from interface: Char2ReferenceMap
        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.

        Specified by:
        getOrDefault in interface Char2ReferenceFunction<V>
        Specified by:
        getOrDefault in interface Char2ReferenceMap<V>
        Specified by:
        getOrDefault in interface Function<java.lang.Character,​V>
        Specified by:
        getOrDefault in interface java.util.Map<java.lang.Character,​V>
        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.

      • putAll

        public void putAll​(java.util.Map<? extends java.lang.Character,​? extends V> m)
        Specified by:
        putAll in interface java.util.Map<java.lang.Character,​V>
      • char2ReferenceEntrySet

        public ObjectSet<Char2ReferenceMap.Entry<V>> char2ReferenceEntrySet()
        Description copied from interface: Char2ReferenceMap
        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:
        char2ReferenceEntrySet in interface Char2ReferenceMap<V>
        Returns:
        a type-specific set view of the mappings contained in this map.
        See Also:
        Map.entrySet()
      • keySet

        public CharSet keySet()
        Description copied from interface: Char2ReferenceMap
        Specified by:
        keySet in interface Char2ReferenceMap<V>
        Specified by:
        keySet in interface java.util.Map<java.lang.Character,​V>
        Returns:
        a set view of the keys contained in this map.
        See Also:
        Map.keySet()
      • values

        public ReferenceCollection<V> values()
        Description copied from interface: Char2ReferenceMap
        Specified by:
        values in interface Char2ReferenceMap<V>
        Specified by:
        values in interface java.util.Map<java.lang.Character,​V>
        Returns:
        a set view of the values contained in this map.
        See Also:
        Map.values()
      • forEach

        public void forEach​(java.util.function.BiConsumer<? super java.lang.Character,​? super V> consumer)
        Specified by:
        forEach in interface Char2ReferenceMap<V>
        Specified by:
        forEach in interface java.util.Map<java.lang.Character,​V>
      • isEmpty

        public boolean isEmpty()
        Specified by:
        isEmpty in interface java.util.Map<java.lang.Character,​V>
