Examples

The following example uses the SetIterator.value method to print the value of the current item in the set.

{ 
    Set s1 = new Set (Types::Integer); 
    SetIterator it; 
  
    // Add some elements 
    s1.add(3); 
    s1.add(4); 
    s1.add(13); 
    s1.add(1);  
  
    // Start a traversal of the elements in the set 
    it = new SetIterator(s1); 
     
    // Prints "(begin)[1]" 
    print it.toString();  
     
    // The elements are fetched in the order: 1, 3, 4, 13 
    while (it.more()) 
    { 
        print it.value(); 
  
        // Fetch the next element 
        it.next(); 
    } 
    pause; 
}
