  • Code formatting when using pointers

    - by HD-VRSCA
    Is there any reason why the asterisk is next to the object type in this code? I'm a little confused by the way I see this used. Some times it looks like this: NSString* stringBefore; and sometimes like this: NSString *stringBefore; Is there a difference? Or a right or wrong way to do this? Thanks

  • Can I change an NSDictionaries key?

    - by Mark Reid
    I have an NSDictionary object that is populated by NSMutableStrings for its keys and objects. I have been able to change the key by changing the original NSMutableString with the setString: method. They key however remains the same regardless of the contents of the string used to set the key initially. My question is, is the key protected from being changed meaning it will always be the same unless I remove it and add another to the dictionary? Thanks.

  • linq subquery child collection to string

    - by bill
    Hi All, i am trying to figure out how to write a linq query that will return a child collections "name" property as a string. I have a BO that has a "options" property where the options are the "name" property of each option in an "order" object. I would like the result to look something like order.id = 12312 order.date = 12/03/10 order.options = "Option 1 Name, Option 2 Name, Option 3 Name" I hope this makes sense. thanks for any and all help!

  • Why do I have to pay for something that I'm not using?

    - by Knowing me knowing you
    Guys just finished reading one of my college books about threads in Java and I was informed that lock - what ever it is, is in Object class. So it looks like even though I'm not using threaded classes my objects will be heavier because of that? Don't you think that it's a bit annoying and unfair to expect from anyone to pay for something s/he have not intention of using? Thanks

  • When not to use a private field

    - by coffeeaddict
    When should it be considered dangerous to use a private field all over the place in the methods of your class? I mostly just create the variable and set it to a default value like null. Then in my methods reference it and set it to an instance of that object type from the methods. I don't know if my question makes sense but let me know if it doesn't and I'll clarify.

  • Usage of initialize() vs. setup() in Mootools

    - by RyOnLife
    Mootools classes have an initialize() method that's called when a new object is instantiated. It seems that setup() is a commonly used method as well. Most classes I've observed call this.setup() from initialize() and nowhere else, which has left me wondering: What's the purpose of setup()? Why not just put the setup() code in initialize()? When does it make sense to use a setup() method?
