Class RegexPatternSetReferenceStatement

java.lang.Object

software.amazon.awssdk.services.wafv2.model.RegexPatternSetReferenceStatement

All Implemented Interfaces:

Serializable, SdkPojo, ToCopyableBuilder<RegexPatternSetReferenceStatement.Builder,RegexPatternSetReferenceStatement>

@Generated(value="software.amazon.awssdk:codegen")
public final class RegexPatternSetReferenceStatement
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<RegexPatternSetReferenceStatement.Builder,RegexPatternSetReferenceStatement>

A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet.

Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, WAF automatically updates all rules that reference it.

Method Detail

arn

public final String arn()

The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.

Returns:

The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.

fieldToMatch

public final FieldToMatch fieldToMatch()

The part of the web request that you want WAF to inspect.

Returns:

The part of the web request that you want WAF to inspect.

hasTextTransformations

public final boolean hasTextTransformations()

For responses, this returns true if the service returned a value for the TextTransformations property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

textTransformations

public final List<TextTransformation> textTransformations()

Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, WAF performs all transformations on the content of the request component identified by FieldToMatch, starting from the lowest priority setting, before inspecting the content for a match.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasTextTransformations() method.

Returns:

Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, WAF performs all transformations on the content of the request component identified by FieldToMatch, starting from the lowest priority setting, before inspecting the content for a match.
