      For each job id, it returns frequency distribution of failed constraints (simple name of constraint) in an unmodifiable map.
      Returns:

    • getCodesToReason

      public Map<Integer,String> getCodesToReason()
      Returns an unmodifiable map of codes and reason pairs.
      Returns:

    • getFailedConstraintNamesToCode

      public Map<String,Integer> getFailedConstraintNamesToCode()
      Returns an unmodifiable map of constraint names (simple name of constraint) and reason code pairs.
      Returns:
