ListtoList(AstNode... nodes)
to List 
List<AstNode> list = new ArrayList<AstNode>();
for (AstNode node : nodes) {
    list.add(node);
return list;
ScriptabletoRegExp(String source, String optionsString)
to Reg Exp 
Context context = Context.getCurrentContext();
Scriptable scope = ScriptRuntime.getTopCallScope(context);
return context.newObject(scope, "RegExp", new Object[] { source, optionsString });
StringtoString(Object val)
to String 
return ScriptRuntime.toString(val);
voidtrace(Object object)
trace 
trace(object, "");
voidtraceHelper(Function function, Object... args)
Get a snapshot of the current JavaScript evaluation state by creating an Error object and invoke the function on it passing along any arguments. 
Context cx = Context.getCurrentContext();
Scriptable scope = ScriptableObject.getTopLevelScope(function);
EcmaError error = ScriptRuntime.constructError("Trace", "");
WrapFactory wrapFactory = cx.getWrapFactory();
Scriptable thisObj = wrapFactory.wrapAsJavaObject(cx, scope, error, null);
for (int i = 0; i < args.length; i++) {
    args[i] = wrapFactory.wrap(cx, scope, args[i], null);
function.call(cx, scope, thisObj, args);
Objectunwrap(Object obj)
Unwrap a Rhino object (getting the raw java object) and convert undefined to null 
if (obj instanceof Wrapper) {
    obj = ((Wrapper) obj).unwrap();
} else if (obj == Undefined.instance) {
    obj = null;
return obj;
ListunwrapNativeArray(final NativeArray na)
unwrap Native Array 
return new ArrayList<Object>() {
        for (int i = 0; i < na.getLength(); ++i) {
            add(unwrapNative(na.get(i, null)));
};
ObjectwrapJavaObj(Object javaObj, Scriptable scope)
Wrap java object to javascript object 
return Context.javaToJS(javaObj, scope);
