Type Parameters:
C - type of container values this provider supplies
All Implemented Interfaces:

public class StatusAwareDataProvider<C extends Containerable> extends MultivalueContainerListDataProvider<C>
Data provider that augments MultivalueContainerListDataProvider with awareness of StatusInfo for each wrapped value.

It maintains two caches:

  • tokenByWrapper – maps each PrismContainerValueWrapper to the status token it belongs to
  • statusByToken – maps a token string to the corresponding StatusInfo
These caches allow efficient lookup of suggestion status for both the current page and all loaded items.

  • Field Details

    • statusByToken

      protected final Map<String,com.evolveum.midpoint.smart.api.info.StatusInfo<?>> statusByToken
      Cache of status information keyed by token.

    • tokenByWrapper

      protected final Map<PrismContainerValueWrapper<C extends Containerable>,String> tokenByWrapper
      Cache of wrappers mapped to their status token (identity-based).

    • postProcessWrapper

      protected void postProcessWrapper(@NotNull @NotNull PrismContainerValueWrapper<C> vw)
      Overrides:
      postProcessWrapper in class MultivalueContainerListDataProvider<C extends Containerable>

    • getSuggestionInfo

      @Nullable public @Nullable com.evolveum.midpoint.smart.api.info.StatusInfo<?> getSuggestionInfo(PrismContainerValueWrapper<C> vw)
      Returns the current StatusInfo for the given value wrapper.

      If the wrapper is not yet cached, the suggestionResolver is applied, and the token/status are stored. The status is then refreshed using the SmartIntegrationService, ensuring up-to-date information.

      Parameters:
      vw - wrapper whose suggestion status should be resolved
      Returns:
      the latest StatusInfo, or null if none is available

      Overrides:
      detach in class BaseSearchDataProvider<C extends Containerable,PrismContainerValueWrapper<C extends Containerable>>

    • primeSuggestionCacheForAll

      public void primeSuggestionCacheForAll()
      Optionally warm the cache for all rows (not just current page).

    • getAllSelected

      public List<PrismContainerValueWrapper<C>> getAllSelected()

    • applyInitialSorting

      protected void applyInitialSorting()
      Configures the initial sort state for this data provider.

      By default, no explicit sorting is applied (setSort(null)), meaning items are presented in their natural or source-defined order.

      Subclasses may override this method to define a custom default sort, for example to prioritize suggested or existing mappings: 

      
 @Override
 protected void applyInitialSorting() {
     // Sort by "name" property in ascending order
     setSort(new SortParam<>("name", true));
 }

      In the context of mapping tables, different item types (e.g. suggestions vs. existing mappings) may define distinct default sorting strategies.
