    109=== Include and exclude ===
    11 You can include and exclude classes in the mask by calling the corresponding functions. Including/Excluding a class usually applies not only to the specified class but to all subclasses too.

    4342=== Operators ===

    45 It's possible to calculate with masks in the meaning of set-theory, so you can create unions (+), intersections (*), differences (-) and complements (!) by using the corresponding operators.

    73 Performance of ClassTreeMaskObjectIterator is good as long as you don't exclude subclasses of included classes. Of course you can still exlucde subclasses, but if this is done more often, we need a new implementation using a second ObjectList in the Identifier, containing all objects of exactly one class. Including subclasses of excluded classes however is really fast.
