Method Detail

onEventError

public final void onEventError(List<com.googlecode.jpattern.shared.result.IErrorMessage> errorMessages)

Specified by:

onEventError in interface IPresenter

public final void onEventStart()

Description copied from interface: IPresenter

getView

protected final T getView()

preDisplay

public abstract void preDisplay()

This method is called before the rendered of the IView. It should be better to not perform asynchronous actions in this method.

postDisplay

public abstract void postDisplay()

This method is called after the rendered of the IView. Here the asynchronous actions should be performed. Its VERY important to call the endLoading() method when all the actions are performed otherwise the IView should not be displayed.

endLoading

public final void endLoading()

This method must be called when all the necessary operations to load necessary data are endend. This causes the final rendering of the IView.
