Generic Function: RUCKSACK-MAP-CLASS

Documentation

FUNCTION is a unary function that gets called for all instances of the specified class. Unindexed classes (i.e. classes for which the :indexed class option is nil) will be skipped. If ID-ONLY is T (default is NIL), the function will be called with object ids instead of 'real' objects. This can be handy if you want to do more filtering before actually loading objects from disk. INCLUDE-SUBCLASSES defaults to T.
