Thanks Paul, your interpretation was correct. I did see Container
before, and while I don't think is going to work in this case, it did
make me think of using the DynamicPropertyHandler to do this. I was
actually considering using the DynamicPropertyHandler for something
else, but didn't think of using it for this purpose.
Basically, what I'm going to try and do is just have my
DynamicPropertyHandler return the normal properties for my class. So in
my example I'd do something like:
public class BarHandler implements DynamicPropertyHandler {
public Object getProperty(Object object, String propertyName) {
if (propertyName.equals("x")) {
return ((Bar) object).getSubContexts();
}
return null;
}
public String[] getPropertyNames(Object object) {
return new String[] { "x" };
}
public void setProperty(Object object, String propertyName, Object
value) {
throw new UnsupportedOperationException("");
}
}
And then something like
JXPathIntrospector.registerDynamicClass(Bar.class, BarHandler.class);
Anyway, will update with the results of this. If anyone sees an obvious
problem with that please let me know.
