Ductape API allows iterators to used in many of its classes. Using iterators will allow you to access member of a datastructor without needing to know the underlying implementation.

One place where you can use iterators is in the pdb class, here is a simple function that iterates over every class in the file printing its name. File to be parsed and analyized:

class bar
{
	int foo(int v)
	{
		return v + 2;
	}	
	class bar2 
	{
		int rountine(bool t) {return 0;}
	};
	int a;
};

C source file:

#include "pdbAll.h"
#include "stdio.h"
	
	int main(int argc, char *argv[]) {
  	
		// Read the pdb file as input for this program.
		PDB p(argv[1]); if ( !p ) return 1;
 
		// Iterate through each class in the pdb file and print its name.
		for (PDB::classvec::iterator r = p.getClassVec().begin();
			r!=p.getClassVec().end(); r++)
		{
			 cout << (*r)->name() << endl;
		}
		return 0;
	}

To run type:

%> g++ -I../inc/ -o vector vector.cc ../lib/libpdb.a 
%> cxxparse testApp.cc 
%> ./vector testApp.pdb 
bar
bar2

There is a collection of example source code in the API documentation.
