Class Object2ReferenceMaps.UnmodifiableMap<K,​V>

    • Method Detail

      • containsValue

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

        public void putAll​(java.util.Map<? extends K,​? extends V> m)
        Specified by:
        putAll in interface java.util.Map<K,​V>
      • object2ReferenceEntrySet

        public ObjectSet<Object2ReferenceMap.Entry<K,​V>> object2ReferenceEntrySet()
        Description copied from interface: Object2ReferenceMap
        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:
        object2ReferenceEntrySet in interface Object2ReferenceMap<K,​V>
        Returns:
        a type-specific set view of the mappings contained in this map.
        See Also:
        Map.entrySet()
      • entrySet

        public ObjectSet<java.util.Map.Entry<K,​V>> entrySet()

        Specified by:
        entrySet in interface java.util.Map<K,​V>
        Specified by:
        entrySet in interface Object2ReferenceMap<K,​V>
        Returns:
        a set view of the mappings contained in this map.

        Description copied from interface: Object2ReferenceMap
        Attempts to compute a mapping for the specified key and its current mapped value (or null if there is no current mapping).

        If the function returns null, the mapping is removed (or remains absent if initially absent). If the function itself throws an (unchecked) exception, the exception is rethrown, and the current mapping is left unchanged.

        Description copied from interface: Object2ReferenceMap
        If the specified key is not already associated with a value, associates it with the given value. Otherwise, replaces the associated value with the results of the given remapping function, or removes if the result is null.

        Parameters:
        key - key with which the resulting value is to be associated.
        value - the value to be merged with the existing value associated with the key or, if no existing value is associated with the key, to be associated with the key.
        remappingFunction - the function to recompute a value if present.
        Returns:
        the new value associated with the specified key, or the default return value if no value is associated with the key.
