The Context class (object) stores the application data and applies the sort strategy selected against the application data.
class Context
{
private List<String> list = new List<String>();
private IStrategy sortStrategy;
public Context(IStrategy sortStrategy) { this.sortStrategy = sortStrategy; }
public void AddItem(String name) { list.Add(name); } public void SetSortStrategy(IStrategy sortStrategy) { this.sortStrategy = sortStrategy; } public void Sort() { this.sortStrategy.Sort(list);
foreach (String name in list) { Console.WriteLine(name); } } }
public Context(IStrategy sortStrategy) { this.sortStrategy = sortStrategy; }
public void AddItem(String name) { list.Add(name); } public void SetSortStrategy(IStrategy sortStrategy) { this.sortStrategy = sortStrategy; } public void Sort() { this.sortStrategy.Sort(list);
foreach (String name in list) { Console.WriteLine(name); } } }
