David Bosschaert commented on FELIX-5678:
-----------------------------------------
Hi [~dleangen],
I think the simplest solution would be to take your 2 objects and convert them
both to simple Maps using the converter. Then you can merge the 2 maps by
calling {{map1.putAll(map2)}}
Finally you can convert your resulting map back to the target object you need
using the converter.
Alternatively you should be able to use a custom converter rule like described
in the first comment, and in more detail here:
[https://osgi.org/specification/osgi.enterprise/7.0.0/util.converter.html#util.converter-customizing.converters]
Let me know if this helps...
Cheers,
David
> Allow merging of objects
> ------------------------
>
> Key: FELIX-5678
> URL: https://issues.apache.org/jira/browse/FELIX-5678
> Project: Felix
> Issue Type: Bug
> Components: Converter
> Reporter: David Leangen
> Priority: Major
>
> Given a typed object O1 and a "partial" representation of an object O2 (for
> instance in the form of a Map), allow O2 to be merged into O1.
> Example:
> {code}
> public class Foo {
> public String a;
> public String b;
> public String c;
> }
> Foo f = new Foo();
> a = "Eh!";
> b = "Be cool.";
> c = "See you later?";
> Map<String, String> m = new Map<>();
> m.put("b", "Be there or be square");
> Foo f2 = Converter.convert(f).merge(m);
> {code}
> I am sure there are many ways to skin this cat.
> If the Converter API cannot be changed, what would be the best way to tackle
> this problem?
> (In the meantime, while awaiting comments form [~bosschaert], I'll try to run
> a few experiments to see if I can come up with something reasonable.)
