Althouh I can very well marshal/unmarshal
typesafe-enum simple properties, I still cannot do it
for a collection (say a List) of instances of this
typesafe enum class.
Any help is welcome! Thanks.
Here is a simple test case that fails:
public class EColors { // a type safe enum
private String name;
private EColors(String name) {
this.name = name;
}
public static final EColors RED = new
EColors("RED");
public static final EColors BLUE = new
EColors("BLUE");
public static final EColors GREEN = new
EColors("GREEN");
public String toString() {
return name;
}
public static EColors valueOf(String name) {
if ("RED".equals(name)) return RED;
if ("GREEN".equals(name)) return BLUE;
if ("BLUE".equals(name)) return GREEN;
return null;
}
}
public class MyObject { // the object to (un)marshal
private EColors color; // this works
private List severalColors; // list of of EColor
instances
public EColors getColor() {
return color;
}
public void setColor(EColors color) {
this.color = color;
}
public List getSeveralColors() {
return severalColors;
}
public void setSeveralColors(List severalColors) {
this.severalColors = severalColors;
}
}
The mapping file:
<mapping>
<class name="test.EColors"
verify-constructable="false" auto-complete="true"/>
<class name="test.MyObject">
<field name="color" type="test.EColors"/>
<!-- what follows does not work -->
<field name="severalColors" collection="arraylist"
type="test.EColors"/>
</class>
</mapping>
The object I marshal:
MyObject mo = new MyObject();
mo.setColor(EColors.BLUE);
List severalColors = new ArrayList();
severalColors.add(EColors.BLUE);
severalColors.add(EColors.GREEN);
mo.setSeveralColors(severalColors);
The output marshalled file (missing the content of my
collection):
<?xml version="1.0" encoding="UTF-8"?>
<my-object><color>BLUE</color><several-colors/><several-colors/></my-object>
