@Generated(value="jsii-pacmak/1.118.0 (build 02eec31)", date="2025-11-10T13:39:59.978Z") @Stability(Stable) public class CfnWaitConditionHandle extends CfnResource implements IInspectable, IWaitConditionHandleRef
The AWS::CloudFormation::WaitConditionHandle type has no properties.

When you reference the WaitConditionHandle resource by using the Ref function, CloudFormation returns a presigned URL. You pass this URL to applications or scripts that are running on your Amazon EC2 instances to send signals to that URL. An associated AWS::CloudFormation::WaitCondition resource checks the URL for the required number of success signals or for a failure signal.

For more information, see Create wait conditions in a CloudFormation template in the AWS CloudFormation User Guide .

Anytime you add a WaitCondition resource during a stack update or update a resource with a wait condition, you must associate the wait condition with a new WaitConditionHandle resource. Don't reuse an old wait condition handle that has already been defined in the template. If you reuse a wait condition handle, the wait condition might evaluate old signals from a previous create or update stack command.

Updates aren't supported for this resource.

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.cloudformation.*;
 CfnWaitConditionHandle cfnWaitConditionHandle = CfnWaitConditionHandle.Builder.create(this, "MyCfnWaitConditionHandle").build();
