> This is *AWS WAF Classic* documentation.
For more information, see AWS WAF Classic in the developer guide.

For the latest version of AWS WAF , use the AWS WAF V2 API and see the AWS WAF Developer Guide . With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Specifies a constraint on the size of a part of the web request. AWS WAF uses the Size , ComparisonOperator , and FieldToMatch to build an expression in the form of " Size ComparisonOperator size in bytes of FieldToMatch ". If that expression is true, the SizeConstraint is considered to match.
Example:
```
 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.waf.regional.*;
 SizeConstraintProperty sizeConstraintProperty = SizeConstraintProperty.builder()
         .comparisonOperator("comparisonOperator")
         .fieldToMatch(FieldToMatchProperty.builder()
                 .type("type")
                 // the properties below are optional
                 .data("data")
                 .build())
         .size(123)
         .textTransformation("textTransformation")
         .build();
 
```

- Method Detail
  - getComparisonOperator
```
java.lang.String getComparisonOperator()
```
    The type of comparison you want AWS WAF to perform.
    AWS WAF uses this in combination with the provided Size and FieldToMatch to build an expression in the form of " Size ComparisonOperator size in bytes of FieldToMatch ". If that expression is true, the SizeConstraint is considered to match.
    EQ : Used to test if the Size is equal to the size of the FieldToMatch
    NE : Used to test if the Size is not equal to the size of the FieldToMatch
    LE : Used to test if the Size is less than or equal to the size of the FieldToMatch
    LT : Used to test if the Size is strictly less than the size of the FieldToMatch
    GE : Used to test if the Size is greater than or equal to the size of the FieldToMatch
    GT : Used to test if the Size is strictly greater than the size of the FieldToMatch
  - getFieldToMatch
```
java.lang.Object getFieldToMatch()
```
    The part of a web request that you want AWS WAF to inspect, such as a specific header or a query string.
  - getSize
```
java.lang.Number getSize()
```
    The size in bytes that you want AWS WAF to compare against the size of the specified `FieldToMatch` .
    AWS WAF uses this in combination with ComparisonOperator and FieldToMatch to build an expression in the form of " Size ComparisonOperator size in bytes of FieldToMatch ". If that expression is true, the SizeConstraint is considered to match.
    Valid values for size are 0 - 21474836480 bytes (0 - 20 GB).
    If you specify URI for the value of Type , the / in the URI path that you specify counts as one character. For example, the URI /logo.jpg is nine characters long.
  - getTextTransformation
```
java.lang.String getTextTransformation()
```
    Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF .
    If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting a request for a match.
    You can only specify a single type of TextTransformation.
    Note that if you choose BODY for the value of Type , you must choose NONE for TextTransformation because the API Gateway API or Application Load Balancer forward only the first 8192 bytes for inspection.
    NONE
    Specify NONE if you don't want to perform any text transformations.
    CMD_LINE
    When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
    - Delete the following characters: \ " ' ^
    - Delete spaces before the following characters: / (
    - Replace the following characters with a space: , ;
    - Replace multiple spaces with one space
    - Convert uppercase letters (A-Z) to lowercase (a-z)
    COMPRESS_WHITE_SPACE
    Use this option to replace the following characters with a space character (decimal 32):
    - \f, formfeed, decimal 12
    - \t, tab, decimal 9
    - \n, newline, decimal 10
    - \r, carriage return, decimal 13
    - \v, vertical tab, decimal 11
    - non-breaking space, decimal 160
    COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.
    HTML_ENTITY_DECODE
    Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
    - Replaces (ampersand)quot; with "
    - Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
    - Replaces (ampersand)lt; with a "less than" symbol
    - Replaces (ampersand)gt; with >
    - Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
    - Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
    LOWERCASE
    Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
    URL_DECODE
    Use this option to decode a URL-encoded value.
  - builder
```
static CfnSizeConstraintSet.SizeConstraintProperty.Builder builder()
```
    Returns:
    
    a CfnSizeConstraintSet.SizeConstraintProperty.Builder of CfnSizeConstraintSet.SizeConstraintProperty
