    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 WAFV2 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.

    A combination of ByteMatchSet, IPSet, and/or SqlInjectionMatchSet objects that identify the web requests that you want to allow, block, or count. For example, you might create a Rule that includes the following predicates:

    • An IPSet that causes AWS WAF to search for web requests that originate from the IP address 192.0.2.44

    • A ByteMatchSet that causes AWS WAF to search for web requests for which the value of the User-Agent header is BadBot.

    To match the settings in this Rule, a request must originate from 192.0.2.44 AND include a User-Agent header for which the value is BadBot.

    • Method Detail

      • ruleId

        public final String ruleId()

        A unique identifier for a Rule. You use RuleId to get more information about a Rule (see GetRule), update a Rule (see UpdateRule), insert a Rule into a WebACL or delete a one from a WebACL (see UpdateWebACL), or delete a Rule from AWS WAF (see DeleteRule).

        RuleId is returned by CreateRule and by ListRules.

        Returns:
        A unique identifier for a Rule. You use RuleId to get more information about a Rule (see GetRule), update a Rule (see UpdateRule), insert a Rule into a WebACL or delete a one from a WebACL (see UpdateWebACL), or delete a Rule from AWS WAF (see DeleteRule).

        RuleId is returned by CreateRule and by ListRules.

      • name

        public final String name()

        The friendly name or description for the Rule. You can't change the name of a Rule after you create it.

        Returns:
        The friendly name or description for the Rule. You can't change the name of a Rule after you create it.

      • metricName

        public final String metricName()

        A friendly name or description for the metrics for this Rule. The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with maximum length 128 and minimum length one. It can't contain whitespace or metric names reserved for AWS WAF, including "All" and "Default_Action." You can't change MetricName after you create the Rule.

        Returns:
        A friendly name or description for the metrics for this Rule. The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with maximum length 128 and minimum length one. It can't contain whitespace or metric names reserved for AWS WAF, including "All" and "Default_Action." You can't change MetricName after you create the Rule.

      • hasPredicates

        public final boolean hasPredicates()
        For responses, this returns true if the service returned a value for the Predicates 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.

      • predicates

        public final List<Predicate> predicates()

        The Predicates object contains one Predicate element for each ByteMatchSet, IPSet, or SqlInjectionMatchSet object that you want to include in a Rule.

        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 hasPredicates() method.

        Returns:
        The Predicates object contains one Predicate element for each ByteMatchSet, IPSet, or SqlInjectionMatchSet object that you want to include in a Rule.

      • serializableBuilderClass

      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
