Delegate

• To create a delegate at the namespace level, create a class with the <<Delegate>> stereotype, and add an operation with the <<Delegate>> stereotype to this class and define a visibility for this operation. This visibility becomes the visibility of the delegate

  
  
  

{
 public delegate int ActionOccurred();
}

• To create a delegate in a class, or structure, you just have to create an operation with the <<Delegate>> stereotype. In the following example, Class worker contains an internal delegate designed as an operation with the <<Delegate>> stereotype

  
  
  

{
 public class Worker
 {
  public delegate  WorkStarted();
 }
}
