Class JSONSerializer

java.lang.Object
  net.sf.json.JSONSerializer

public class JSONSerializer
extends java.lang.Object

Transforms java objects into JSON and back.
Transformation from java to JSON is pretty straightforward, but the other way around needs certain configuration, otherwise the java objects produced will be DynaBeans and Lists, because the JSON notation does not carry any information on java classes.
Use the provided property setters before calling toJava().

JSONSerializer()
Default constructor

JSONSerializer(java.lang.Class rootClass, java.util.Map classMap, int arrayMode)
Constructs a new JSONSerializer with specific values for conversion.

Method Summary

int	getArrayMode() Returns the current array mode conversion
java.util.Map	getClassMap() Returns the current attribute/class Map
java.lang.Class	getRootClass() Returns the current root Class.
void	reset() Resets this serializer to default values. rootClass = null classMap = null arrayMode = MODE_LIST
void	setArrayMode(int arrayMode) Sets the current array mode for conversion. If the value is not MODE_LIST neither MODE_OBJECT_ARRAY, then MODE_LIST will be used.
void	setClassMap(java.util.Map classMap) Sets the current attribute/Class Map
void	setRootClass(java.lang.Class rootClass) Sets the current root Class
java.lang.Object	toJava(JSON json) Transform a JSON value to a java object. Depending on the configured values for conversion this will return a DynaBean, a bean, a List, or and array.
static JSON	toJSON(java.lang.Object object) Creates a JSONObject, JSONArray or a JSONNull from object.
