CfnRuleProps

class aws_cdk.core.CfnRuleProps(*, assertions=None, rule_condition=None)

Bases: object

__init__(*, assertions=None, rule_condition=None)

A rule can include a RuleCondition property and must include an Assertions property. For each rule, you can define only one rule condition; you can define one or more asserts within the Assertions property. You define a rule condition and assertions by using rule-specific intrinsic functions.

You can use the following rule-specific intrinsic functions to define rule conditions and assertions:

Fn::And Fn::Contains Fn::EachMemberEquals Fn::EachMemberIn Fn::Equals Fn::If Fn::Not Fn::Or Fn::RefAll Fn::ValueOf Fn::ValueOfAll

Parameters

• assertions (Optional[List[CfnRuleAssertion]]) – Assertions which define the rule. Default: - No assertions for the rule.

• rule_condition (Optional[ICfnConditionExpression]) – If the rule condition evaluates to false, the rule doesn’t take effect. If the function in the rule condition evaluates to true, expressions in each assert are evaluated and applied. Default: - Rule’s assertions will always take effect.

Attributes
