That's simple - there are no function pointers in this case. ;-) The design is
flexible and allows for dynamically-changed constraints, but it also allows for
completely static constraints, the latter being the case here. A constraint is a
predicate - that's all. You can use boost::function to be able to dynamically
change the constraint, or you can use a predicate directly as the template's
parameter to make it statically associated with the type of used constrained
objects.
Best regards,
