Rhino: return JSON from within Java

Question

I have the string representation of a JSON-serialized object in Java e.g. \"{\\\"name\\\":\\\"John\\\",\\\"age\\\":24}\". How do I parse and return it to the JavaSc

Answer 1

The latest version of Rhino has only four args, and the fourth cannot be null. To solve this, you must create a simple class that implements org.mozilla.javascript.Callable:

import org.mozilla.javascript.Callable;
import org.mozilla.javascript.Context;
import org.mozilla.javascript.Scriptable;

public class NullCallable implements Callable
{
    @Override
    public Object call(Context context, Scriptable scope, Scriptable holdable, Object[] objects)
    {
        return objects[1];
    }
}

You can then call NativeJSON.parse like this:

Object result = NativeJSON.parse(context, scope, jsonString, new NullCallable());
