    • forceUppercase

      public static String forceUppercase(Class<?> dataObjectClass, String fieldName, String fieldValue)
      Uses the DataDictionary to determine whether to force uppercase the value, and if it should, then it does the uppercase, and returns the upper-cased value.
      Parameters:
      dataObjectClass - parent DO class that the fieldName is a member of
      fieldName - name of the field to be forced to uppercase
      fieldValue - value of the field that may be uppercased
      Returns:
      the correctly uppercased fieldValue if it should be uppercased, otherwise fieldValue is returned unchanged

    • forceUppercase

      public static Map<String,String> forceUppercase(Class<?> dataObjectClass, Map<String,String> fieldValues)
      Uses the DataDictionary to determine whether to force uppercase the values, and if it should, then it does the uppercase, and returns the upper-cased Map of fieldname/fieldValue pairs.
      Parameters:
      dataObjectClass - parent DO class that the fieldName is a member of
      fieldValues - a Mapinvalid input: '<'String,String> where the key is the fieldName and the value is the fieldValue

      Parameters:
      dataObjectClass - class to get limit for
      lookupForm - lookupForm to use. May be null if the form is unknown. If lookupForm is null, only the dataObjectClass will be used to find the search results set limit

    • isExternalBusinessObjectProperty

      public static boolean isExternalBusinessObjectProperty(Object sampleBo, String propertyName)
