Annotation Interface StyleSheet

@Retention(RUNTIME) @Target(TYPE) @Documented @Repeatable(Container.class) public @interface StyleSheet
Defines style sheet dependencies on a Component class. For adding multiple style sheets for a single component, you can use this annotation multiple times.

It is guaranteed that dependencies will be loaded only once.

NOTE: while this annotation is not inherited using the @Inherited annotation, the annotations of the possible parent components or implemented interfaces are read when sending the dependencies to the browser.
