  • How to access a (shadowed) global function in ruby.

    - by yngvedh
    Hi, I was wondering how to access a global function fn in ruby from a class which also defined a method fn. I have made a workaround by aliasing the function like so: def fn end class Bar alias global_fn fn def fn # how to access the global fn here without the alias global_fn end end I'm looking for something along the lines of c++'s :: to access global scope but I can't seem to locate any information about it. I guess I don't know specifically what I'm looking for.

  • DBTransaction Rollback throws

    - by pdiddy
    Looking into the documentation it says that the Rollback method can throw when the transaction is not in pending state (after begin transaction and before commit transaction). I can't seem to find a way to check whether the transaction can be rollback or not. There isn't a state property either.

  • Subclassing Cocoa means no subclass ivars in some cases?

    - by Michael
    The question is generally coming from self = [super init]. In case if I'm subclassing NSSomething and in my init's method self = [super init] returns object of different class, does it mean I am not able to have my very own ivars in my subclass, just because self will be pointing to different class? Appreciate if you could bring some examples if my statement is wrong.

  • Prototype with a callback problem

    - by Lisio
    function Foo() { this.bar = false; } Foo.prototype={ onLoad: function() { this.bar=true; }, create: function(id) { SomeClass.someMethod({ id: id, onWorkIsDone: this.onLoad }); } }; var temp=new Foo(); temp.create(); This sample has a logic error in string 'onWorkIsDone: this.onLoad'.

  • Passing data to notification page

    - by FRKT
    I'm not sure what the best way of populating a notification page is. I've been using sessions to populate it with information, but this falls short if the user is blocking cookies. I've considered passing it in HTTP GET variables, but I'm unsure whether it's a good alternative since its length is limited by some browsers. Which method do you prefer?

  • Java Multi threading - Avoid duplicate request processing

    - by seawaves
    I have following multi threaded environment scenario - Requests are coming to a method and I want to avoid the duplicate processing of concurrent requests coming. As multiple similar requests might be waiting for being processed in blocked state. I used hashtable to keep track of processed request, but it will create memory leaks, so how should keep track of processed request and avoid the same requests to be processed which may be in blocking state.

    - by moonese
    If I create a scheduled task by calling ScheduledExecutorService.schedule(), it never quits after execution, is it a JDK bug, or I just miss something? note: doSomething() is empty method below. public static void doSomething() { } public static void main(String[] args) { ScheduledFuture scheduleFuture = Executors.newSingleThreadScheduledExecutor().schedule(new Callable() { public Void call() { try { doSomething(); } catch (Exception e) { e.printStackTrace(); } return null; } }, 1, TimeUnit.SECONDS); }
