Documentation
FUNCTION is a unary function that gets called for all instances of
the specified class that have a slot value matching the EQUAL, MIN,
MAX INCLUDE-MIN and INCLUDE-MAX arguments (see the documentation of
MAP-INDEX for a description of these arguments).
ORDER can be either :ASCENDING (default) or :DESCENDING; currently,
the specified order will be respected for instances of one class but
not across subclasses.
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.
