// UpdateRegexPatternSetRequest returns a request value for making API operation for

//
// This is AWS WAF Classic documentation. For more information, see AWS WAF
// Classic (https://docs.aws.amazon.com/waf/latest/developerguide/classic-waf-chapter.html)
// in the developer guide.
//
// For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS
// WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html).
// With the latest version, AWS WAF has a single set of endpoints for regional
// and global use.
//
// Inserts or deletes RegexPatternString objects in a RegexPatternSet. For each
// RegexPatternString object, you specify the following values:
//
//    * Whether to insert or delete the RegexPatternString.
//
//    * The regular expression pattern that you want to insert or delete. For
//    more information, see RegexPatternSet.
//
// For example, you can create a RegexPatternString such as B[a@]dB[o0]t. AWS
// WAF will match this RegexPatternString to:
//
//    * BadBot
//
//    * BadB0t
//
//    * B@dBot
//
//    * B@dB0t
//
// To create and configure a RegexPatternSet, perform the following steps:
//
// Create a RegexPatternSet. For more information, see CreateRegexPatternSet.
//
// Use GetChangeToken to get the change token that you provide in the ChangeToken
// parameter of an UpdateRegexPatternSet request.
//
// Submit an UpdateRegexPatternSet request to specify the regular expression
// pattern that you want AWS WAF to watch for.
//
// For more information about how to use the AWS WAF API to allow or block HTTP
// requests, see the AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/).
//
//    // Example sending a request using UpdateRegexPatternSetRequest.
//    req := client.UpdateRegexPatternSetRequest(params)
//    resp, err := req.Send(context.TODO())
//    if err == nil {
//        fmt.Println(resp)
