Re: [json-lib-user] serializing to new <Object>(<parameters>)

Yes, you can but it may not turn out to be exactly as you would expect.

You can register a JsonBeanProcessor or a JsonValueProcessor that takes
care of marshalling the property, you'll need to return a valid JSON value
[JSON,null,Number,String,Boolean,JSONFunction] so in your case you'll
return a String, something like "new Date( <params> )", which means that
when the json string is deserialized on the browser the date won't be automatically
created.

Enabling arbitrary JS code as property value is a big no-no in many circles but
I can clearly see the advantages of doing so, specially if you have the proper
security measures in place. Perhaps this can be added as a feature.

Cheers,
Andres

Is it possible, using json-lib, to serialize an object to a javascript new operator call. 

For instance, to serialize to a Date value, I would serialize it to new Date(<here go the constructor parameters>). 


Thanks

This is what I suspected. Because there is no JSON*** object to emulate an object constructor call. 

For now I will just simply extend the json.org api (which was incorporated to this lib) to generate the constructor call.
