Core.PDFNet. DictIterator

new DictIterator()

DictIterator is used to traverse key/value pairs in a dictionary. For example a DictIterator can be used to print out all the entries in a given Obj dictionary as follows: 
 DictIterator itr = dict.GetDictIterator();
 while (itr.HasNext()) {
     Obj key = itr.Key();
	    cout << key.GetName() << endl;
     Obj value = itr.Value();
     // ...
     itr.Next()
  }
