io.meeds.appcenter.storage.ApplicationCategoryStorage
@Component public class ApplicationCategoryStorage extends Object

    List<Long>
    getApplicationIds(long categoryId)

    • getApplicationIds

      @Cacheable(cacheNames="app-center.category.apps", key="#p0", sync=true) public List<Long> getApplicationIds(long categoryId)
      Reads the ids of the applications linked to a category or to any of its sub-categories, whatever their depth: the category's own links first, then its sub-categories' in the order the category service returns them, each application once. Nothing in the value depends on the viewer: access, activation and order are decided by the caller on each read. The links of applications are stored under the application id as is, since ApplicationCategoryPlugin does not rewrite the linked object, so the list read of links needs no plugin normalisation.
      Parameters:
      categoryId - the selected category
      Returns:
      the linked application ids, never null, not modifiable

    • clearCache

      @CacheEvict(cacheNames="app-center.category.apps", allEntries=true) public void clearCache()
      Clears every category's applications: a link, a category creation, move or deletion can change any subtree.
