Class ImmutableClassToInstanceMap<B>

    • Method Detail

      • copyOf

        public static <B,​S extends B> ImmutableClassToInstanceMap<B> copyOf​(Map<? extends Class<? extends S>,​? extends S> map)
        Returns an immutable map containing the same entries as map. If map somehow contains entries with duplicate keys (for example, if it is a SortedMap whose comparator is not consistent with equals), the results of this method are undefined.

        Note: Despite what the method name suggests, if map is an ImmutableClassToInstanceMap, no copy will actually be performed.

        NullPointerException - if any key or value in map is null
        ClassCastException - if any value is not an instance of the type specified by its key
      • getInstance

        public <T extends B> T getInstance​(Class<T> type)
        Description copied from interface: ClassToInstanceMap
        Returns the value the specified class is mapped to, or null if no entry for this class is present. This will only return a value that was bound to this specific class, not a value that may have been bound to a subtype.
        Specified by:
        getInstance in interface ClassToInstanceMap<B>
      • putInstance

        public <T extends B> T putInstance​(Class<T> type,
                                           T value)
        Unsupported operation.
        Guaranteed to throw an exception and leave the map unmodified.
        Specified by:
        putInstance in interface ClassToInstanceMap<B>
        the value previously associated with this class (possibly null), or null if there was no previous entry.
        UnsupportedOperationException - always
