For NavigationResource, create an InfoNavigationPrototype that implements the NavigationResource.Info interface as in the following example:

/**
 * Navigation prototype for Info operation.
 */
public class InfoNavigationPrototype implements NavigationResource.Info {
 
	private static final Single<ResourceInfo> INFO_SINGLE = Single.just(ResourceInfo.builder()
			.withMaxAge(NavigationsResourceConstants.MAX_AGE)
			.build());
 
	@Override
	public Single<ResourceInfo> onInfo() {
		return INFO_SINGLE;
	}
}
Copy

In the prototype, a ResourceInfo is built and the max-age for the resource is returned.
