Interface SharedBetaFactStorage

public interface SharedBetaFactStorage

  • Method Details

    • ensureDeltaCapacity

      void ensureDeltaCapacity​(int insertCount)

    • delete

      boolean delete​(RuntimeFact fact)

    • insert

      boolean insert​(RuntimeFact fact)

      The method first reads the fact's key (values of specific fields) and checks if any of main and delta repositories contain such a key. If they don't, a new key will be created in the delta repository, the fact will be stored there under this key, and the method will return true. If the key is already known, the fact will be appended to the corresponding repository, and the method will return false.

      Parameters:
      fact - fact to process
      Returns:
      true if the fact's field values (the storage key) are unknown to either delta and main scopes

    • insertDirect

      void insertDirect​(RuntimeFact fact)
