What is the problem?
The following interface:
export namespace CfnRuleGroup {
/**
* @stability external
* @link http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-networkfirewall-rulegroup-ipset.html
*/
export interface IPSetProperty {
/**
* `CfnRuleGroup.IPSetProperty.Definition`
* @link http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-networkfirewall-rulegroup-ipset.html#cfn-networkfirewall-rulegroup-ipset-definition
*/
readonly definition?: string[];
}
}gets translated into the following Python:
@jsii.interface(
jsii_type="@aws-cdk/aws-networkfirewall.CfnRuleGroup.IPSetProperty"
)
class IPSetProperty(typing_extensions.Protocol):
'''
:link: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-networkfirewall-rulegroup-ipset.html
'''
@builtins.staticmethod
def __jsii_proxy_class__() -> typing.Type["_IPSetPropertyProxy"]:
return _IPSetPropertyProxy
@builtins.property # type: ignore[misc]
@jsii.member(jsii_name="definition")
def definition(self) -> typing.Optional[typing.List[builtins.str]]:
'''``CfnRuleGroup.IPSetProperty.Definition``.
:link: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-networkfirewall-rulegroup-ipset.html#cfn-networkfirewall-rulegroup-ipset-definition
'''
...which makes it unusable for CDK Python users.
