    • Method Detail

      • containsValue

        public boolean containsValue​(boolean v)
        Description copied from interface: Reference2BooleanMap
        Returns true if this map maps one or more keys to the specified value.
        Specified by:
        containsValue in interface Reference2BooleanMap<K>

        @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 K,​? extends java.lang.Boolean> m)

      • reference2BooleanEntrySet

        public ObjectSet<Reference2BooleanMap.Entry<K>> reference2BooleanEntrySet()
        Description copied from interface: Reference2BooleanMap
        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:
        reference2BooleanEntrySet in interface Reference2BooleanMap<K>
        Returns:
        a type-specific set view of the mappings contained in this map.

      • keySet

        public ReferenceSet<K> keySet()
        Description copied from interface: Reference2BooleanMap

        Note that this specification strengthens the one given in Map.keySet().

        Specified by:
        keySet in interface java.util.Map<K,​java.lang.Boolean>
        Specified by:
        keySet in interface Reference2BooleanMap<K>
        Returns:
        a set view of the keys contained in this map.

      • values

        public BooleanCollection values()
        Description copied from interface: Reference2BooleanMap

        Note that this specification strengthens the one given in Map.values().

        Specified by:
        values in interface java.util.Map<K,​java.lang.Boolean>
        Specified by:
        values in interface Reference2BooleanMap<K>
        Returns:
        a set view of the values contained in this map.
