Re: [Simple-support] Dynamic object type determination

[Niall G. <gal...@ya...>]

Hi,

I am sure you could use a strategy here and write your own way of determining the type. The persister will simply ask the strategy, what is the type for this XML element. The strategy then provides an object with the details. There should be some examples in the test cases of this.

You should then be able to do.

MyStrategy x = ...
Persister p = new Persister(x);
Object o = p.read(Object.class, xml);
