onClassesChange

public void onClassesChange(HotswapClassEvent event)

Description copied from interface: VaadinHotswapper

Called by Vaadin hotswap entry point when one or more application classes have been updated.

This method is meant to perform application-wide updates. Operation targeting Vaadin session should be implemented in VaadinHotswapper.onClassesChange(HotswapClassSessionEvent) method.

Currently, the default implementation delegates to the deprecated VaadinHotswapper.onClassLoadEvent(VaadinService, Set, boolean) method for backward compatibility.

Specified by:

onClassesChange in interface VaadinHotswapper

Parameters:

event - the event instance carrying the information about the changed classes.

changedClasses - the classes that have been added or modified
