This module contains the classes used to represent Amazon S3 Event Notifications.

To convert a json notification to java classes, use the static methods available on S3EventNotification:

String json = "..."; // the notification as json
S3EventNotification event = S3EventNotification.fromJson(json);
event.getRecords().forEach(rec -> println(rec.toString()));

Any missing fields of the json will be null in the resulting object. Any extra fields will be ignored.

To convert an instance of S3EventNotification to json, use the .toJson() or toJsonPretty() method:

S3EventNotification event = new S3EventNotification(...);
String json = event.toJson();
String jsonPretty = event.toJsonPretty();

GlacierEventData, ReplicationEventData, IntelligentTieringEventData and LifecycleEventData will be excluded from the json if null. Any other null fields of the object will be serialized in the json as null.
