Subject RE: recommendation requested: json translation into objects

Google gson? I think that's a clever name. Gson looks like it smartly
attacks this problem. I love the fact it supports generics. Thanks for the
reference.


I think the small code snippet in an earlier response helps, the only
problem is that some objects don't serialize/deserialize very well (no fault
of pivot) and I want to have custom translation much like pivot does with
paint deserialization from a json string so that I have a simpler-than-xml
way to represent some objects and markup, specifically around affine
transformations for the SVG component I recently posted.

For my single object needs, I'll do it like pivot with a single converter,
although it would be nice if pivot had a ConverterService to be called by
any component to translate from json string to an object...pivot could load
its converters and other people could write theirs and contribute them with
a standard mechanism.  But is not an essential service to pivot today.

I've had good experiences with Google's Gson:

http://code.google.com/p/google-gson/

though I don't know if it would be suitable here.  It has some nice
features, like being able to turn [1,2,3,4,5] into a
java.util.List<Integer>.  It can also do things like turn
[{'x':1},{'x':2},{'x':3},{'x':4},{'x':5}] into a List<Foo>, if you have

class Foo {
    int x;
}
