-- * 'lrpsNextMarker' - If you specify a value for @Limit@ and you have more @RegexPatternSet@ objects than the value of @Limit@ , AWS WAF returns a @NextMarker@ value in the response that allows you to list another group of @RegexPatternSet@ objects. For the second and subsequent @ListRegexPatternSets@ requests, specify the value of @NextMarker@ from the previous response to get information about another batch of @RegexPatternSet@ objects.
--
-- * 'lrpsLimit' - Specifies the number of @RegexPatternSet@ objects that you want AWS WAF to return for this request. If you have more @RegexPatternSet@ objects than the number you specify for @Limit@ , the response includes a @NextMarker@ value that you can use to get another batch of @RegexPatternSet@ objects.
