Recall that well-known superclasses
of balanced graphs are perfect graphs and hereditary clique-Helly graphs.
The characters [chi]X are referred to as supercharacters and the sets K [member of] K are called superclasses
Subclasses are not included in the attributes of the class because they could be inspired by considering the superclasses
list of subclasses.
Classes are organized into a subclass hierarchy such that the prescribed attributes of superclasses
can be inherited by the subclasses.
Moreover, all integrity constraints that apply to superclasses
are inherited "naturally" by their subclasses.
We mention earlier that superclasses
and subclasses are best retained together for intersite distribution.
We will refer to the parts of K as superclasses
, and for some fixed choice of scalars [c.
The application has a reasonably rich class hierarchy including superclasses
, inner classes, static and private variables, class variables and constructors.
In embedded prototyping, all the methods valid on an object are contained in the object itself, that is, they are not searched for in a list of superclasses
OP5: Change the ordering of superclasses
of a class C: Simply change
c) the supercharacters are constant on superclasses
The second condition in the definition of class structure also implies that, in a class structure, a specialized class must have properties not possessed by any of its superclasses
