## Interface ModificationWatchpointRequest

- All Superinterfaces:
    EventRequest, Mirror, WatchpointRequest

      @Exported
      public interface ModificationWatchpointRequest
      extends WatchpointRequest

  Request for notification when a field is set. This event will be triggered when a value is assigned to the specified field with a JavaTM programming language statement (assignment, increment, etc) or by a Java Native Interface (JNI) set function (`Set<Type>Field, SetStatic<Type>Field`). Setting a field to a value which is the same as the previous value still triggers this event. Modification by JDI does not trigger this event. When an enabled ModificationWatchpointRequest is satisfied, an `event set` containing a `ModificationWatchpointEvent` will be placed on the `EventQueue`. The collection of existing watchpoints is managed by the `EventRequestManager`.
  Since:
    1.3
