public static AWSWAFClientBuilder builder()
```
  - createByteMatchSet
```
public CreateByteMatchSetResult createByteMatchSet(CreateByteMatchSetRequest request)
```
    Creates a ByteMatchSet. You then use UpdateByteMatchSet to identify the part of a web request that you want AWS WAF to inspect, such as the values of the User-Agent header or the query string. For example, you can create a ByteMatchSet that matches any requests with User-Agent headers that contain the string BadBot. You can then configure AWS WAF to reject those requests.
    
    To create and configure a ByteMatchSet, perform the following steps:
    1. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateByteMatchSet request.
    2. Submit a CreateByteMatchSet request.
    3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateByteMatchSet request.
    4. Submit an UpdateByteMatchSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value 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.

  - createIPSet
```
public CreateIPSetResult createIPSet(CreateIPSetRequest request)
```
    Creates an IPSet, which you use to specify which web requests you want to allow or block based on the IP addresses that the requests originate from. For example, if you're receiving a lot of requests from one or more individual IP addresses or one or more ranges of IP addresses and you want to block the requests, you can create an IPSet that contains those IP addresses and then configure AWS WAF to block the requests.
    
    To create and configure an IPSet, perform the following steps:
    1. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateIPSet request.

  - createRule
```
public CreateRuleResult createRule(CreateRuleRequest request)
```
    Creates a Rule, which contains the IPSet objects, ByteMatchSet objects, and other predicates that identify the requests that you want to block. If you add more than one predicate to a Rule, a request must match all of the specifications to be allowed or blocked. For example, suppose you add the following to a Rule:
    - An IPSet that matches the IP address 192.0.2.44/32
    - A ByteMatchSet that matches BadBot in the User-Agent header
    You then add the Rule to a WebACL and specify that you want to blocks requests that satisfy the Rule. For a request to be blocked, it must come from the IP address 192.0.2.44 and the User-Agent header in the request must contain the value BadBot.
    
    To create and configure a Rule, perform the following steps:
    1. Create and update the predicates that you want to include in the Rule. For more information, see CreateByteMatchSet, CreateIPSet, and CreateSqlInjectionMatchSet.
    2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateRule request.
    3. Submit a CreateRule request.
    4. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRule request.
    5. Submit an UpdateRule request to specify the predicates that you want to include in the Rule.
    6. Create and update a WebACL that contains the Rule. For more information, see CreateWebACL.

  - createWebACL
```
public CreateWebACLResult createWebACL(CreateWebACLRequest request)
```
    Creates a WebACL, which contains the Rules that identify the CloudFront web requests that you want to allow, block, or count. AWS WAF evaluates Rules in order based on the value of Priority for each Rule.
    
    You also specify a default action, either ALLOW or BLOCK. If a web request doesn't match any of the Rules in a WebACL, AWS WAF responds to the request with the default action.
    
    To create and configure a WebACL, perform the following steps:
    1. Create and update the ByteMatchSet objects and other predicates that you want to include in Rules. For more information, see CreateByteMatchSet, UpdateByteMatchSet, CreateIPSet, UpdateIPSet, CreateSqlInjectionMatchSet, and UpdateSqlInjectionMatchSet.
    2. Create and update the Rules that you want to include in the WebACL. For more information, see CreateRule and UpdateRule.
    3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateWebACL request.
    4. Submit a CreateWebACL request.
    5. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateWebACL request.
    6. Submit an UpdateWebACL request to specify the Rules that you want to include in the WebACL, to specify the default action, and to associate the WebACL with a CloudFront distribution.
    For more information about how to use the AWS WAF API, see the AWS WAF Developer Guide.

  - getChangeToken
```
public GetChangeTokenResult getChangeToken(GetChangeTokenRequest request)
```
    When you want to create, update, or delete AWS WAF objects, get a change token and include the change token in the create, update, or delete request. Change tokens ensure that your application doesn't submit conflicting requests to AWS WAF.
    
    Each create, update, or delete request must use a unique change token. If your application submits a GetChangeToken request and then submits a second GetChangeToken request before submitting a create, update, or delete request, the second GetChangeToken request returns the same value as the first GetChangeToken request.
    
    When you use a change token in a create, update, or delete request, the status of the change token changes to PENDING, which indicates that AWS WAF is propagating the change to all AWS WAF servers. Use GetChangeTokenStatus to determine the status of your change token.

  - getSampledRequests
```
public GetSampledRequestsResult getSampledRequests(GetSampledRequestsRequest request)
```
    Gets detailed information about a specified number of requests--a sample--that AWS WAF randomly selects from among the first 5,000 requests that your AWS resource received during a time range that you choose. You can specify a sample size of up to 500 requests, and you can specify any time range in the previous three hours.
    
    GetSampledRequests returns a time range, which is usually the time range that you specified. However, if your resource (such as a CloudFront distribution) received 5,000 requests before the specified time range elapsed, GetSampledRequests returns an updated time range. This new time range indicates the actual period during which AWS WAF selected the requests in the sample.

  - updateByteMatchSet
```
public UpdateByteMatchSetResult updateByteMatchSet(UpdateByteMatchSetRequest request)
```
    Inserts or deletes ByteMatchTuple objects (filters) in a ByteMatchSet. For each ByteMatchTuple object, you specify the following values:
    - Whether to insert or delete the object from the array. If you want to change a ByteMatchSetUpdate object, you delete the existing object and add a new one.
    - The part of a web request that you want AWS WAF to inspect, such as a query string or the value of the User-Agent header.
    - The bytes (typically a string that corresponds with ASCII characters) that you want AWS WAF to look for. For more information, including how you specify the values for the AWS WAF API and the AWS CLI or SDKs, see TargetString in the ByteMatchTuple data type.
    - Where to look, such as at the beginning or the end of a query string.
    - Whether to perform any conversions on the request, such as converting it to lowercase, before inspecting it for the specified string.
    For example, you can add a ByteMatchSetUpdate object that matches web requests in which User-Agent headers contain the string BadBot. You can then configure AWS WAF to block those requests.
    
    To create and configure a ByteMatchSet, perform the following steps:
    1. Create a ByteMatchSet. For more information, see CreateByteMatchSet.
    2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateByteMatchSet request.
    3. Submit an UpdateByteMatchSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value 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.

  - updateIPSet
```
public UpdateIPSetResult updateIPSet(UpdateIPSetRequest request)
```
    Inserts or deletes IPSetDescriptor objects in an IPSet. For each IPSetDescriptor object, you specify the following values:
    - Whether to insert or delete the object from the array. If you want to change an IPSetDescriptor object, you delete the existing object and add a new one.
    - The IP address version, IPv4 or IPv6.
    - The IP address in CIDR notation, for example, 192.0.2.0/24 (for the range of IP addresses from 192.0.2.0 to 192.0.2.255) or 192.0.2.44/32 (for the individual IP address 192.0.2.44).
    AWS WAF supports /8, /16, /24, and /32 IP address ranges for IPv4, and /24, /32, /48, /56, /64 and /128 for IPv6. For more information about CIDR notation, see the Wikipedia entry Classless Inter-Domain Routing.
    
    IPv6 addresses can be represented using any of the following formats:
    - 1111:0000:0000:0000:0000:0000:0000:0111/128
    - 1111:0:0:0:0:0:0:0111/128
    - 1111::0111/128
    - 1111::111/128
    You use an IPSet to specify which web requests you want to allow or block based on the IP addresses that the requests originated from. For example, if you're receiving a lot of requests from one or a small number of IP addresses and you want to block the requests, you can create an IPSet that specifies those IP addresses, and then configure AWS WAF to block the requests.
    
    To create and configure an IPSet, perform the following steps:
    1. Submit a CreateIPSet request.
    2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.
    3. Submit an UpdateIPSet request to specify the IP addresses that you want AWS WAF to watch for.
    When you update an IPSet, you specify the IP addresses that you want to add and/or the IP addresses that you want to delete. If you want to change an IP address, you delete the existing IP address and add the new one.
    
    For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

  - updateRule
```
public UpdateRuleResult updateRule(UpdateRuleRequest request)
```
    Inserts or deletes Predicate objects in a Rule. Each Predicate object identifies a predicate, such as a ByteMatchSet or an IPSet, that specifies the web requests that you want to allow, block, or count. If you add more than one predicate to a Rule, a request must match all of the specifications to be allowed, blocked, or counted. For example, suppose you add the following to a Rule:
    - A ByteMatchSet that matches the value BadBot in the User-Agent header
    - An IPSet that matches the IP address 192.0.2.44
    You then add the Rule to a WebACL and specify that you want to block requests that satisfy the Rule. For a request to be blocked, the User-Agent header in the request must contain the value BadBot and the request must originate from the IP address 192.0.2.44.
    
    To create and configure a Rule, perform the following steps:
    1. Create and update the predicates that you want to include in the Rule.
    2. Create the Rule. See CreateRule.
    3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRule request.
    4. Submit an UpdateRule request to add predicates to the Rule.
    5. Create and update a WebACL that contains the Rule. See CreateWebACL.
    If you want to replace one ByteMatchSet or IPSet with another, you delete the existing one and add the new one.
    
    For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

  - updateSizeConstraintSet
```
public UpdateSizeConstraintSetResult updateSizeConstraintSet(UpdateSizeConstraintSetRequest request)
```
    Inserts or deletes SizeConstraint objects (filters) in a SizeConstraintSet. For each SizeConstraint object, you specify the following values:
    - Whether to insert or delete the object from the array. If you want to change a SizeConstraintSetUpdate object, you delete the existing object and add a new one.
    - The part of a web request that you want AWS WAF to evaluate, such as the length of a query string or the length of the User-Agent header.
    - Whether to perform any transformations on the request, such as converting it to lowercase, before checking its length. Note that transformations of the request body are not supported because the AWS resource forwards only the first 8192 bytes of your request to AWS WAF.
    - A ComparisonOperator used for evaluating the selected part of the request against the specified Size, such as equals, greater than, less than, and so on.
    - The length, in bytes, that you want AWS WAF to watch for in selected part of the request. The length is computed after applying the transformation.
    For example, you can add a SizeConstraintSetUpdate object that matches web requests in which the length of the User-Agent header is greater than 100 bytes. You can then configure AWS WAF to block those requests.
    
    To create and configure a SizeConstraintSet, perform the following steps:
    1. Create a SizeConstraintSet. For more information, see CreateSizeConstraintSet.
    2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateSizeConstraintSet request.
    3. Submit an UpdateSizeConstraintSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value 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.

  - updateWebACL
```
public UpdateWebACLResult updateWebACL(UpdateWebACLRequest request)
```
    Inserts or deletes ActivatedRule objects in a WebACL. Each Rule identifies web requests that you want to allow, block, or count. When you update a WebACL, you specify the following values:
    - A default action for the WebACL, either ALLOW or BLOCK. AWS WAF performs the default action if a request doesn't match the criteria in any of the Rules in a WebACL.
    - The Rules that you want to add and/or delete. If you want to replace one Rule with another, you delete the existing Rule and add the new one.
    - For each Rule, whether you want AWS WAF to allow requests, block requests, or count requests that match the conditions in the Rule.
    - The order in which you want AWS WAF to evaluate the Rules in a WebACL. If you add more than one Rule to a WebACL, AWS WAF evaluates each request against the Rules in order based on the value of Priority. (The Rule that has the lowest value for Priority is evaluated first.) When a web request matches all of the predicates (such as ByteMatchSets and IPSets) in a Rule, AWS WAF immediately takes the corresponding action, allow or block, and doesn't evaluate the request against the remaining Rules in the WebACL, if any.
    To create and configure a WebACL, perform the following steps:
    1. Create and update the predicates that you want to include in Rules. For more information, see CreateByteMatchSet, UpdateByteMatchSet, CreateIPSet, UpdateIPSet, CreateSqlInjectionMatchSet, and UpdateSqlInjectionMatchSet.
    2. Create and update the Rules that you want to include in the WebACL. For more information, see CreateRule and UpdateRule.
    3. Create a WebACL. See CreateWebACL.
    4. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateWebACL request.
    5. Submit an UpdateWebACL request to specify the Rules that you want to include in the WebACL, to specify the default action, and to associate the WebACL with a CloudFront distribution.

  - getCachedResponseMetadata
```
public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
```
    Returns additional metadata for a previously executed successful, request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.
    Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing the request.
    
    Specified by:
