(In Rhino) Why Context.newObje ct() looking for constructors only in TopLevelScope?

This is "newObject" method from org.mozilla.jav ascript.Context class.

01 : public final Scriptable newObject(Scrip table scope, String
constructorName , Object[] args)
02 : {
03 : scope = ScriptableObjec t.getTopLevelSc ope(scope);
04 : Function ctor = ScriptRuntime.g etExistingCtor( this, scope,
05 :
constructorName );
06 : if (args == null) { args = ScriptRuntime.e mptyArgs; }
07 : return ctor.construct( this, scope, args);
08 : }

Why scope gets reset to point to TopLevelScope (line 03)?

Generally the point of ECMAScript is that the author does not need to
know anything about how implementations of the language work. And doing
cross-browser work makes the specific implementations less significant
as they are not the same in different browsers. So long as the resulting
behaviour corresponds with ECMA 262 the internal details are not

A good group for asking questions related to the Spidermonkey and/or
Rhino implementations is - netscape.public .mozilla.jseng -, as there
they may get the attention of the authors of those implementations .

Thanks Richard, I will repost it there.

Hi, I'm in a tightly-secured environment where I may not be allowed to use Python for some scripting work, and may have to fall back on what came with Windows 2K. I'm cracking "VBScript in a Nutshell" from O'Reilly, and have found a number of disappointments: * can't find "Introspection" in the Index * no record types, just numerically-indexed arrays, so record handling is kludgy

Coming from the C++ world I can not understand the reason why copy constructors are not used in the .NET framework. A copy constructor creates an object from a copy of another object of the same kind. It sounds simple but evidently .NET has difficulty with this concept for some reason. I do understand that .NET objects are created on the GC heap but that doesn't mean that they couldn't be copied from another object of the same kind when...

Is it possible to use System.Type, Activator or whatever to create a complete "blank", unitialized object of a given type, and then at a later time call a constructor on it. The only caveat is that before I call the constructor I still want the object to correctly return its type if GetType() is called. If its possible, how do I create the initial object, and how do I then later call the constructor on it? Thanks

Trying to find out what is essential / optional, I made an extremely simple Class and Module combination to add two numbers. (see below) It appears that an empty constructor is needed n order to work right, although I quite don't see what is does in addition to the 2nd constructor. Also, the example works fine without message calls in either constructor (the numerical answer is still there and correct!). I exected it to no longer work...

Hello! Whilst refactoring an application, I was looking at optimizing a ModelFactory with generics. Unfortunately, the business objects created by the ModelFactory doesn't provide public constructors (because we do not allow developers to instantiate them directly). Because our business objects are instantiated very frequently, the idea of using reflection sounds like a performance killer (I haven't done any tests on this, but the...

I have a question: I was wondering if it is possible to simulate the multiple constructors, like in Java (yes, I know that the languages are completely different)? Let's say that I have a class called "Point" which would have two values "x" and "y". Now, let's say if it were the Java version, I would want two constructors: one that accept two numbers, the other accepts a string:

Hi I want to develop a Java application to check the syntax of Javascript code and I am thinking about using Rhino. But I don't know where to start and there is no document for this. Has anybody done this before? or can Rhino be embedded in my Java application to check the syntax of JavaScript code? I thought it is possible. Thanks!

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
