Class JavaToJSONConverters

java.lang.Object

org.htmlunit.corejs.javascript.JavaToJSONConverters

public class JavaToJSONConverters
extends Object

This class provides implementations of converters for Java objects to be used by the JSON.stringify method.

JSON.stringify will automatically convert instances of java.util.Map to javascript objects. Instances of java.util.Collection and java Arrays will be converted to javascript arrays.

This is a final effort at conversion for other java objects that appear as values, and may be preempted by objects which define a toJSON() method or by a replacer function passed to JSON.stringify. The return value will, in turn, be converted according to Context.javaToJS(java.lang.Object, org.htmlunit.corejs.javascript.Scriptable) and stringified.
