- Method Detail
  - lifecycleHookName
```
public final String lifecycleHookName()
```
    The name of the lifecycle hook.
    
    Returns:
    
    The name of the lifecycle hook.
  - lifecycleTransition
```
public final String lifecycleTransition()
```
    The lifecycle transition. For Auto Scaling groups, there are two major lifecycle transitions.
    
    To create a lifecycle hook for scale-out events, specify autoscaling:EC2_INSTANCE_LAUNCHING.
    
    To create a lifecycle hook for scale-in events, specify autoscaling:EC2_INSTANCE_TERMINATING.
    Returns:
    
    The lifecycle transition. For Auto Scaling groups, there are two major lifecycle transitions.
    
    To create a lifecycle hook for scale-out events, specify autoscaling:EC2_INSTANCE_LAUNCHING.
    
    To create a lifecycle hook for scale-in events, specify autoscaling:EC2_INSTANCE_TERMINATING .
  - notificationMetadata
```
public final String notificationMetadata()
```
    Additional information that you want to include any time Amazon EC2 Auto Scaling sends a message to the notification target.

  - heartbeatTimeout
```
public final Integer heartbeatTimeout()
```
    The maximum time, in seconds, that can elapse before the lifecycle hook times out. The range is from 30 to 7200 seconds. The default value is 3600 seconds (1 hour).

  - defaultResult
```
public final String defaultResult()
