[Simple-support] Serializing Enums

[Alvin B. <alv...@gm...>]

Hi

I'm trying to serialize an enum that looks like this:

public enum Category {
....
    NEWSPAPER(Type.SUBSCRIPTION) {
@Override
 public String getPrintable() {
    return "Newspaper Subscription Fee";
 }
    },
    MAGAZINE(Type.SUBSCRIPTION) {
@Override
public String getPrintable() {
    return "Magazine Subscription Fee";
}
    },
    MEMBERSHIP(Type.SUBSCRIPTION) {
 @Override
public String getPrintable() {
    return "Club Membership Fee";
 }
    },
....
}

But when serializing it throws this exception:

org.simpleframework.xml.transform.TransformException: Transform of class
com.epik.dto.expense.Category$48 not supported

 at com.epik.client.BillClient.<init>(BillClient.java:23)
at com.epik.client.BillClient.main(BillClient.java:74)

The top class of the exception (AbstractClient), and the line that
generates the exception is this:

Serializer s = new Persister(new EpikMatcher());
StringWriter writer = new StringWriter();
s.write(resource, writer); //Exception generated Here


The matcher looks like this:

public class EpikMatcher implements Matcher {

    @SuppressWarnings("rawtypes")
    @Override
    public Transform match(Class clazz) throws Exception {
if (clazz.equals(DateTime.class)) {
    return new DateTimeAdapter();
}
return null;
    }
}

It serializes when the enum doesn't implement an abstract method (as does
mine), but as I implement an abstract method, it crashes.

Thanks for any help
