structure5
Class OrderedVector<E extends Comparable<E>>

java.lang.Object
  structure5.AbstractStructure<E>
      structure5.OrderedVector<E>

All Implemented Interfaces:

Iterable<E>, OrderedStructure<E>, Structure<E>

public class OrderedVector<E extends Comparable<E>>
extends AbstractStructure<E>
implements OrderedStructure<E>

Implementation of an ordered structure implemented using a vector. Values are stored within this vector in increasing order. All values stored within an ordered vector must implement comparable.

Example Usage:

To determine the effect of the original Starwars™ movie on the careers of its stars, we could place ComparableAssociations between each star's name and the number of movies they have been in since Starwars™ into an ordered vector and print our the results.

 public static void main(String[] argv){
        //instantiate an ordered vector
        OrderedVector> v = new #OrderedVector>();
        
        //add the cast members of the original star wars along with
        //the number of films in which the have subsequently appeared
        v.add(new ComparableAssociation(new Integer(12),"Sir Alec Guiness"));
        v.add(new ComparableAssociation(new Integer(24),"Carrie Fisher"));
        v.add(new ComparableAssociation(new Integer(28),"Harrison Ford")); 
        v.add(new ComparableAssociation(new Integer(28),"Mark Hamill"));

        //print out the results
        for(Iterator> i = v.iterator(); i.hasNext();){
            ComparableAssociation> actor = i.next();
            System.out.println(actor.getValue() + " has been in " + 
                               actor.getKey() + " movies since Star Wars"); 
        }
   }
