![Events Diagram](../assets/images/events@2x.png)

Here’s a [sample event listener](https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/PrintEventsNonConcurrent.java) that prints each event with a timestamp.

```java

```

In this case, the `startup` event handler function will initialize the items "database" (just a `dict`) with some values.

You can add more than one event handler function.

And your application won't start receiving requests until all the `startup` event handlers have completed.

### `shutdown` event

To add a function that should be run when the application is shutting down, declare it with the event `"shutdown"`:

	UserAgent    string
}

// ToEvent - converts to notification event.
func (args eventArgs) ToEvent(escape bool) event.Event {
	eventTime := UTCNow()
	uniqueID := fmt.Sprintf("%X", eventTime.UnixNano())
	if !args.Object.ModTime.IsZero() {
		uniqueID = fmt.Sprintf("%X", args.Object.ModTime.UnixNano())
	}

	respElements := map[string]string{
		"x-amz-request-id": args.RespElements["requestId"],

	NamespaceFormat = "namespace"

	// AccessFormat - access log format used in some event targets.
	AccessFormat = "access"

	// AMZTimeFormat - event time format.
	AMZTimeFormat = "2006-01-02T15:04:05.000Z"

	// StoreExtension - file extension of an event file in store
	StoreExtension = ".event"
)

// Identity represents access key who caused the event.
type Identity struct {

type GetObjectContext struct {
	OutputRoute string `json:"outputRoute"`
	OutputToken string `json:"outputToken"`
	InputS3URL  string `json:"inputS3Url"`
}

// Event represents lambda function event, this is undocumented in AWS S3. This
// structure bases itself on this structure but there is no binding.
//
//	{
//	  "xAmzRequestId": "a2871150-1df5-4dc9-ad9f-3da283ca1bf3",
//	  "getObjectContext": {
//	    "outputRoute": "...",
