[Simple-support] de/serializing class delegating read-only property.

[N. N. <nju...@gm...>]

how would one use SimpleXML to serialize/deserialize the following
prototypical example class?  the basic premise is that the class delegates
some read-only properties to a subordinate class.  the subordinate class, in
turn, must be initialized on instantiation (because its properties are
read-only).

i'd like to have the XML look something like <delegateProperty
propertyA="100" propertyB="200"/> (or as attributes) but can't figure out
how to appropriately annotate with SimpleXML.  thanks for any help.

public class DelegatedProperty
{
    public DelegatedProperty(int propertyA, int propertyB)
    {
        this.delegate = new Delegate(propertyA, propertyB);
    }

    public int getPropertyA()
    {
        return this.delegate.getA();
    }

    public int getPropertyB()
    {
        return this.delegate.getB();
    }

    private Delegate delegate = null;
}
