/**
-* This file constructs type information for constant entities.
-*
-* It constructs the information for a class type with a dispatch
-* table. The class has a field a, and two methods f and g. The
-* class is represented by a class type with two entities for the
-* field a and the reference to the dispatch table. This reference
-* is a constant entity. Ther dispatch table is also represented
-* by a class type that contains the two methods. There is one entity
-* of the dispatch table which is constant.
-*
-* Further the example shows the representation of a constant global
-* array.
-*
-* class C {
-* int a;
-* void f();
-* void g(int);
-* }
-* int[4] arre = (7, 2, 13, 92);
