Re: [Simple-support] How to deserialize an heterogeneous sequence of elements

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

Hi,

Very shortly you will be able to do this, via something like this.

@VariantList({
   @ElementList(entry="cleanDir", type=CleanDirCommand.class),
   @ElementList(entry="copy", type=CopyCommand.class)
})
private List<Command> commands;

I have nearly completed this. It should be released in about a week or two. At the moment you would have to use the @Convert annotation and write a converter.
