      equals in class Object
      Parameters:
      obj - Another strategy
      Returns:

      int hashCode()
      Overrides:
      hashCode in class Object

    • createIdentifierLoader

      options - Loading options configured by the requester (who requested mass indexing, ...).
      Returns:
      An entity identifier loader.
