Class GridConfigurationCache

  • All Implemented Interfaces:
    OBProvidable, OBSingleton

    public class GridConfigurationCache
    extends Object
    implements OBSingleton
    Cache that stores the System Grid Configuration and Tab Grid Configuration. It uses a TimeInvalidatedCache to avoid initializing this information too often. To avoid the potential case where we store several times the same configuration (e.g. every tab that has no configuration will use the system one), we cache separately the system and the tab ones and we compose them into a JSONObject with the getGridConfigurationForTab method. If this information changes, some time will passed until the update is reflected on the cache (see expireAfterDuration in cache builder)
