    • createRegexMatchingValidator

      public static Validator createRegexMatchingValidator(Pattern pattern, boolean evaluateExpressions)

    • createRegexValidator

      public static Validator createRegexValidator(int minCapturingGroups, int maxCapturingGroups, boolean supportAttributeExpressionLanguage)
      Creates a @{link Validator} that ensure that a value is a valid Java Regular Expression with at least minCapturingGroups capturing groups and at most maxCapturingGroups capturing groups. If supportAttributeExpressionLanguage is set to true, the value may also include the Expression Language, but the result of evaluating the Expression Language will be applied before the Regular Expression is performed. In this case, the Expression Language will not support FlowFile Attributes but only System/JVM Properties
      Parameters:
      minCapturingGroups - minimum capturing groups allowed
      maxCapturingGroups - maximum capturing groups allowed
      supportAttributeExpressionLanguage - whether or not to support expression language
      Returns:
      validator
