Encoding json

[Richard Salz <rs...@us.ibm.com>]

So, how would you encode json, assuming no limits on nesting depth?

Right now I'm thinking of "flattening" the structure, where you get the 
full name as list<string>, and the value as a string, which is either a 
simple value or empty, and you look for children to get the value of the 
aggregate.

Any thoughts?

I guess I wasn't clear.  It's not about other languages, it's about how 
you'd do it in thrift IDL.

In Perl, it's trivial.  The JSON module from CPAN will round-trip any 
arbitrary structure of any depth into a JSON string in a very efficient 
manner.  See http://search.cpan.org/~makamaka/JSON-2.50/lib/JSON.pm

use JSON;
$encoder = JSON->new();
$json_string = JSON->encode( $complex_structure );
$new_struct = JSON->decode( $json_string );

For Java, it appears that JSONStringer provides similar functionality 
although it's limited to 20 levels.  I haven't personally used it, 
however.  See: http://www.json.org/javadoc/org/json/JSONStringer.html

You can embed Perl inside a Java program using PLJava -

You can embed Java inside a Perl program using Inline::Java -
