There are two examples in this folder. The first one is an adoption of a
multi-inheritance C++ example found on the D. M. Capper book "Introducing
C++ for Scientists, Engineers and Mathematicians" published by
Springer-Verlag. It uses dynamic predicates for storing state. The second
example is a variant of the first one using parametric objects.
This example defines the following objects:
space
this object space stores spatial coordinates using a dynamic
predicate
time
this object stores a time stamp using a dynamic predicate
space_time
this object inherits from both the objects space and time
space(_,_,_)
similar to object space but using parameters instead of dynamic
predicates
time(_)
similar to object space but using a parameter instead of a dynamic
space_time(_,_,_,_)
this object inherits from both the objects space(_,_,_) and time(_)
