--
-- Updates the specified RegexPatternSet.
--
-- This operation completely replaces the mutable specifications that you
-- already have for the regex pattern set with the ones that you provide to
-- this call. To modify the regex pattern set, retrieve it by calling
-- GetRegexPatternSet, update the settings as needed, and then provide the
-- complete regex pattern set specification to this call.
--
-- When you make changes to web ACLs or web ACL components, like rules and
-- rule groups, WAF propagates the changes everywhere that the web ACL and
-- its components are stored and used. Your changes are applied within
-- seconds, but there might be a brief period of inconsistency when the
-- changes have arrived in some places and not in others. So, for example,
-- if you change a rule action setting, the action might be the old action
-- in one area and the new action in another area. Or if you add an IP
-- address to an IP set used in a blocking rule, the new address might
-- briefly be blocked in one area while still allowed in another. This
-- temporary inconsistency can occur when you first associate a web ACL
-- with an Amazon Web Services resource and when you change a web ACL that
-- is already associated with a resource. Generally, any inconsistencies of
-- this type last only a few seconds.
