Annotation Interface LoadDependenciesOnStartup

@Retention(RUNTIME) @Target(TYPE) public @interface LoadDependenciesOnStartup
Defines routes to load eagerly.

All dependencies for the routes you add to this annotation will be loaded when the user first opens the application. Dependencies for other routes will be loaded when the corresponding route is visited the first time.

Define the classes you want to load eagerly as parameters, e.g. @LoadDependenciesOnStartup({MainView.class, TheOtherEntryPointView.class}) to load the MainView and TheOtherEntryPointView.

If you this annotation without any parameters, i.e. @LoadDependenciesOnStartup() then the dependencies for all routes will be loaded on startup.

This annotation must be added to the class implementing AppShellConfigurator.
