Class S3EventSerializer<T>

java.lang.Object
com.amazonaws.services.lambda.runtime.serialization.events.serializers.S3EventSerializer<T>
All Implemented Interfaces:
OrgJsonSerializer<T>, PojoSerializer<T>
public class S3EventSerializer<T> extends Object implements OrgJsonSerializer<T>
Serializer for S3 event NOTE: Because the s3 event class provided by the SDK does not play well with Jackson through a class laoder, this class uses the low level org json library to serialize and deserialize the event. If new events are added that do not work well with Jackson or GSON, this is the fallback method that will always work but is more verbose.
