I'm wondering how to implement prototypal inheritance in Python. It seems like the way to do this would be to either
use a metaclass to cause instantiations to actually be classes, rather than objects, or
use some magical powers to transform an existing object into a class.
The second method would seem to be more flexible, in that it could be applied to existing objects of varied types, while the first would likely be more convenient for typical use cases.
Insights on the practicality of these two approaches, as well as alternative suggestions, are hereby requested.
Hello,
To get the type of a class called myClass I do this
Type myType = (typeof(myClass))
How about, instead of having myClass, I've rather the instanceOfMyClass? How do I get the type?
Let's say I've this
Contact contact = new Contact();
If I want to know which type is contact, how do I do it
Thanks for helping
In light of this question I thought it'd be really neat to have a similar question about C#/.Net.
So, what is the most awkward or misleading method name of the .Net and/or C# API?
Is it possible to reliably determine the compilation time stamp of a given class for both java applications running locally and as applets and/or JNLP webapps ?

Hi all,
I have downloaded the PHP class from github which is the wrapper for their Open Graph API. I can log in and list freinds and images etc. But what I am really struggling with is allowing for extended permissions to allow posting to a users wall.
I know somewhere I need to add "scope=publish_stream" to allow this option and can only assume it is on the getLoginUrl method but I am having next to know joy with it.
Can anyone help me.
Steve
I would like to call a method passing a parameter every 20 seconds,
e.g.
public void ProcessPerson(IPerson person)
I’ve been reading through the different Timer options and was wondering if anybody could recommend the most efficient way to do this?
Thank you for your help.
I know that you can get a reference to a static method like this:
typedef void (*pointer)();
pointer p = &MyClass::MyMethod;
But is there a way to get a reference to the class itself?
I develop a game that has a big number of buttons (25).
I want to know if i can access them without initiating them in interface (.h) in my implementation class.
What's the main point behind putting variables and method signatures inside ApplicationDelegate.h in Objective-C ? By doing this, all those methods and variables are seen by another view controller classes? Is that the point?
And also: is there only one application delegate class inside each project?
How would I go about ensuring that the overridden parent method exists before I call it?
I've tried this:
public function func() {
if (function_exists('parent::func')) {
return parent::func();
}
}
However the function_exists never evaluates to true.
I am trying to create new object of other class in a for loop. like
for(int i =0;i<10;i++){
Computer p1=new Computer(10,20);
}
and when I try anywhere to reach p1.someAction(); it say you must declare p1. But if I declare it on top of program how can I create again in loop? I also try only Computer p1; but it gave exeption ..
I use a stateless session and the follow HQL.

I use the DAO method Execute to delete some records. If this fails this is clear by checking RecordsAffected (it will be 0). But is it possible to get the error message (for instance, to log or to show to the user)? I've try to delete the records by hand in the Table grid I get a clear dialog message, e.g. "The record cannot be deleted or changed because tabel x includes related records".
I have developed an application using Eclipse IDE. After creating the application I exported the project in jar format. When I am trying to run this jar file, I get the error: Unable to load main class. Please Help.
I instantiate the HttpWebRequest object:
HttpWebRequest httpWebRequest =
WebRequest.Create("http://game.stop.com/webservice/services/gameup")
as HttpWebRequest;
When I "post" the data to this service, how does the service know which web method to submit the data to?
I do not have the code to this web service, all I know is that it was written in Java.
in the navigator i can only see the current class' members.
is there a way to include the parents' members.
cause it is very useful when working with a framework, then you don't have to look for them in the documentation.
i think this is available in eclipse but not netbeans.
