Class ObjectSetToStringSetMarshaller

java.lang.Object

com.amazonaws.mobileconnectors.dynamodbv2.dynamodbmapper.marshallers.ObjectSetToStringSetMarshaller

All Implemented Interfaces:

ArgumentMarshaller, ArgumentMarshaller.StringSetAttributeMarshaller

public final class ObjectSetToStringSetMarshaller
extends java.lang.Object
implements ArgumentMarshaller.StringSetAttributeMarshaller

A legacy marshaller that marshals sets of arbitrary Java objects into DynamoDB StringSets by using String.valueOf(Object). Retained for backwards compatibility in case someone is relying on this, but logs a warning if ever used since we only know how to unmarshal back to Java Strings.
