Annotation Type RouteAlias

public @interface RouteAlias

Defines the route alias for components that function as navigation targets in routing.

The route alias allows declaring several route paths in addition to the path declared by the Route annotation. The component has to have at least one @Route annotation which is considered as a primary route and its route path will be used if Router.getUrl(Class) is called. Thus @RouteAlias route path is used only to resolve the component during navigation.

This annotation can be used multiple times on the same class.

Element Detail

value

public abstract String value

Gets the route alias path value of the annotated class.

Returns:

the path value of this route

layout

public abstract Class<? extends RouterLayout> layout

Sets the parent component for the route target component.

When navigating between components that use the same layout, the same component instance is reused. Default layout target is the UI, but the layout should not be a custom UI as UI is a special class used to know where the route stack ends and no parent layouts should be involved.

All layout stacks will be appended to the UI as it represents the Body element.

Returns:

the layout component class used by the route target component.

public abstract boolean absolute

Have the route chain break on defined class and not take into notice any more parent layout route prefixes.

route up to here should be absolute

false
