Class ReloadMainController

java.lang.Object
  |
  +--com.myarch.reloader.ReloadMainController

All Implemented Interfaces:

LoadController

public class ReloadMainController

extends java.lang.Object

implements LoadController

Makes Reloader to re-load only the main class. Main class is the one that was explicitly passed to reload() as a parameter. All other classes won't be re-loaded. This controller is default for Reloader

It is the most simple way to manipulate dynamic reloading. Simply use Reloader for ALL classes that are supposed to be reloadable, do not call classes directly. You will have to create an interface for each class.
