Re: [Simple-support] ElementMap with unknown child elements

[Max S. <ma...@se...>]

Hi,

I repost to the mailing list, so everybody gets the result. What you
need - at least it works - is a Converter for your Parent class:

public class ParentConverter implements Converter<Parent> {
    @Override
    public Parent read(InputNode arg0) throws Exception {
        Parent newParent = new Parent();

        InputNode curNode;
        while ((curNode = arg0.getNext()) != null) {
            newParent.children.put(curNode.getName(), curNode.getValue());
        }

        return newParent;
    }

    @Override
    public void write(OutputNode arg0, Parent arg1) throws Exception {
        for (Entry<String, String> curEntry : arg1.children.entrySet()) {
            OutputNode newNode = arg0.getChild(curEntry.getKey());
            newNode.setValue(curEntry.getValue());
            newNode.commit();
        }
    }
}

So that this will be used to serialize/deserialize your Parent object,
you need to do the following (actually add the
"@Convert(ParentConverter.class)" annotation):

@Convert(ParentConverter.class)
public class Parent {
    public HashMap<String,String> children = new HashMap<>();
}

Simple will only use the Convert annotation, if you create your
Persister object by passing an AnnotationStrategy:

Strategy strategy = new AnnotationStrategy();
Serializer serializer = new Persister(strategy);

But attention: Using this converter will ignore any other annotations
you did in your class, so you actually have to implement the full
reading and writing in the converter!

I just got another idea. Let me check this ...

Best regards
Max
