    public static class Short2IntMaps.EmptyMap
    extends Short2IntFunctions.EmptyFunction
    implements Short2IntMap, java.io.Serializable, java.lang.Cloneable
    An immutable class representing an empty type-specific map.

    This class may be useful to implement your own in case you subclass a type-specific map.

    • Method Detail

      • containsValue

        public boolean containsValue​(int v)
        Description copied from interface: Short2IntMap
        Returns true if this map maps one or more keys to the specified value.
        Specified by:
        containsValue in interface Short2IntMap
        See Also:

      • getOrDefault

        @Deprecated
        public java.lang.Integer getOrDefault​(java.lang.Object key,
                                              java.lang.Integer defaultValue)
        Deprecated.
        Description copied from interface: Short2IntMap
        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 Function<java.lang.Short,​java.lang.Integer>
        Specified by:
        getOrDefault in interface java.util.Map<java.lang.Short,​java.lang.Integer>
        Specified by:
        getOrDefault in interface Short2IntFunction
        Specified by:
        getOrDefault in interface Short2IntMap
        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.

      • containsValue

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

      • putAll

        public void putAll​(java.util.Map<? extends java.lang.Short,​? extends java.lang.Integer> m)
        Specified by:
        putAll in interface java.util.Map<java.lang.Short,​java.lang.Integer>
      • short2IntEntrySet

        public ObjectSet<Short2IntMap.Entry> short2IntEntrySet()
        Description copied from interface: Short2IntMap
        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:
        short2IntEntrySet in interface Short2IntMap
        Returns:
        a type-specific set view of the mappings contained in this map.

      • keySet

        public ShortSet keySet()
        Description copied from interface: Short2IntMap
        Specified by:
        keySet in interface java.util.Map<java.lang.Short,​java.lang.Integer>
        Specified by:
        keySet in interface Short2IntMap
        Returns:
        a set view of the keys contained in this map.

      • values

        public IntCollection values()
        Description copied from interface: Short2IntMap

        Specified by:
        values in interface Short2IntMap
        Returns:
        a set view of the values contained in this map.
