Declaring Generic Collection Classes
All the Tools.h++ generic collection classes are declared as in the example above, using the
declare macro defined in the header file . However, there is one important
difference in how the Tools.h++ classes are declared versus the pattern set by Stroustrup (1986,
Section 7.3.5). The difference is summarized below:
typedef int* intP;
declare(RWGStack, intP) //Wrong!
declare(RWGStack, int) //Correct.
In Stroustrup, the class is declared using a typedef for a pointer to the collected item. The
Rogue Wave generic classes are all declared using the item name itself. This is true for both the
reference-semantics and value-semantics classes.
