Method Detail

jsonToJava

public static Object jsonToJava(String json)

This method returns a Java representation of the given JSON String. The Java data structure created will be created using Map's, String's, Long's, Float's, Boolean's, and List's as specified by the JSON String.

javaToJSON

public static String javaToJSON(Object obj,
                                int depth)

This method attempts to convert the given Object into a JSON String to given depth. If -1 (or lower) is supplied for depth, it will walk upto a default depth of 10 levels of the given Object. If 0 is supplied, it will simply return "". 1 will encode the current Object, but no children. 2 will encode the given Object and its direct children (if any), and so on.

Strings, Longs, Float, and primitives are considered to not have child Objects. Objects which have a public no-argument getXYZ() method are considered to be child Objects. Maps and Collections will be walked.
