// 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 a regex pattern set, do the
// following:
// - Retrieve it by calling GetRegexPatternSet
// - Update its settings as needed
// - 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.
