public interface UiHandler

This is the marker interface for a handler of action(s) in the context of a user-interface (UI). An actual handler is a particular interface extending this one that specifies action operations for events triggered from the view (UI). These are typically implemented by the controller or presenter following the MVC or MVP paradigm. Such action operations shall be methods that start with the prefix on and are followed with the name of the event that has been triggered.
For examples see e.g. UiHandlerEventClick.onClick(net.sf.mmm.client.ui.api.event.UiEventClick) , UiHandlerActionCancel.onCancel(net.sf.mmm.client.ui.api.event.UiEvent) , UiHandlerObjectDelete.onDelete(Object, net.sf.mmm.client.ui.api.event.UiEvent) , or UiHandlerActionSave.onSave(net.sf.mmm.client.ui.api.event.UiEvent) .
