Re: [Simple-support] deserializing a list of subclasses

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

Hi,

Yes this is possible, this and other strategy based questions are probably the most common questions asked. So, I will make sure there are several new entries in the tutorial to describe how to use them. For now there is a good example in the following test case.


http://simple.svn.sourceforge.net/viewvc/simple/trunk/download/stream/src/test/java/org/simpleframework/xml/core/InterceptorTest.java?revision=1128&view=markup

Here you would change the logic slightly to ensure that serialization does not include the class attribute and that deserialization maps the element name to the class.

Hope this helps,
Niall
