      • containsValue

        public boolean containsValue​(double v)
        Description copied from interface: Reference2DoubleMap
        Returns true if this map maps one or more keys to the specified value.

      • getOrDefault

        @Deprecated
        public java.lang.Double getOrDefault​(java.lang.Object key,
                                             java.lang.Double defaultValue)
        Deprecated.
        Description copied from interface: Reference2DoubleMap
        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 Reference2DoubleFunction<K>
        Specified by:
        getOrDefault in interface Reference2DoubleMap<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.

      • reference2DoubleEntrySet

        public ObjectSet<Reference2DoubleMap.Entry<K>> reference2DoubleEntrySet()
        Description copied from interface: Reference2DoubleMap
        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:
        reference2DoubleEntrySet in interface Reference2DoubleMap<K>
        Returns:
        a type-specific set view of the mappings contained in this map.

      • keySet

        public ReferenceSet<K> keySet()
        Description copied from interface: Reference2DoubleMap
        Specified by:
        keySet in interface java.util.Map<K,​java.lang.Double>
        Specified by:
        keySet in interface Reference2DoubleMap<K>
        Returns:
        a set view of the keys contained in this map.

      • values

        public DoubleCollection values()
        Description copied from interface: Reference2DoubleMap

        values in interface java.util.Map<K,​java.lang.Double>
        Specified by:
        values in interface Reference2DoubleMap<K>
        Returns:
        a set view of the values contained in this map.
