Re: [eclipselink-users] XML attributes on the fly? How?

Hi John,

The XmlAnyAttribute will only pick up attributes that aren't otherwise 
mapped. For each attribute encountered, it will check to see if there's 
a field on the object that's mapped to that attribute. If there's not, 
then it's handed off to the XmlAnyAttribute.

The List of objects wouldn't be easy to configure, in part due to the 
fact that the attribute name (source-0, source-1, source-2) changes for 
each instance of the Object. I believe the XmlAnyAttribute would be the 
easiest way to map this, but if you could use a custom accessor method 
to convert from the map to the list and back.

For example:

public class SourceWrapper {
    public String source;

    public String masterSource;
}


public class Region {
    ...
    private List<SourceWrapper> source;
    ...

@XmlTransient
public List<SourceWrapper> getSource() {
    return source;
}

@XmlAnyAttribute
public Map<QName, String> getSourceMap() {
    HashMap<QName, String> map = new HashMap<QName, String>();
    for(int i = 0; i < channels; i++) {
        Source next = source.get(i);
        map.put(new QName("source-" + i), next.source);
        map.put(new QName("masterSource-" + 1), next.masterSource);
    }
    return map;
}
public void setSourceMap(Map<QName, String> map) {
    //build the list of wrappers from the map
}

Hope the helps,

-Matt
