XFormAnswerDataSerializer (javarosa 3.5.0 API)

java.lang.Object
- org.javarosa.xform.util.XFormAnswerDataSerializer

All Implemented Interfaces:

IAnswerDataSerializer
```
public class XFormAnswerDataSerializer
extends Object
implements IAnswerDataSerializer
```
The XFormAnswerDataSerializer takes in AnswerData objects, and provides an XForms compliant (String or Element) representation of that AnswerData. By default, this serializer can properly operate on StringData, DateData MultipleItemsData, and SelectOneData AnswerData objects. This list can be extended by registering appropriate XForm serializing AnswerDataSerializers with this class.
