使用标签属性过滤简单框架中的标签

Question

Now I have this code:

@ElementListUnion({
        @ElementList(entry = "broom", type = Broom.class, inline = true),
        @ElementList(entry = "update", type = Update.class, inline = true)
})
private List<Task> tasks;

With this code I can write in xml these tags:

<broom/>
<update/>

and different classes for this tags will be used.

Now I want to write this xml:

<entry name="broom"/>
<entry name="update"/>

Is it possible to change my annotations, so for these two tags will be used to different classes?

This is not possible, but with a Converter you can solve this.

There you can implement the "if attribute is XY, then ..." part.

Please see here:

• Deserialize XML elements to different types, based on attribute
• demarshalling an xml where attributes determine type
