onClassesChange

public void onClassesChange(HotswapClassSessionEvent 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 updates at VaadinSession level. Operation targeting the entire application should be implemented in VaadinHotswapper.onClassesChange(HotswapClassEvent) method.

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

Specified by:

onClassesChange in interface VaadinHotswapper

Parameters:

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