• Using static vs. member find method on a STL set?

  - by B Johnson

  I am using a set because, i want to use the quick look up property of a sorted container such as a set. I am wondering if I have to use the find member method to get the benefit of a sorted container, or can I also use the static find method in the STL algorithms? My hunch is that using the static version will use a linear search instead of a binary search like I want.

• Does the type in this KVC validation method matter?

  - by dontWatchMyProfile

  For example, in the docs a KVC-style validation method is implemented like this: -(BOOL)validateAge:(id *)ioValue error:(NSError **)outError They used id* as the type for ioValue. Since that's not part of the method signature, I wonder if it would hurt to do something like: -(BOOL)validateAge:(NSNumber *)ioValue error:(NSError **)outError Is this still fine with KVC?

• Static field in class - Is it a re-instantiated for each static method call?

  - by Jamie Dixon

  If I have a static class with a static field such as: private static myField = new myObject(); I then have a bunch of static methods that use myField. Is myField re-instantiated for each method call? My guess is that it's instantiated the first time a method is called that uses it and it remains in memory until the GC clears it up? Cheers for any pointers :-)

• is there a way to see what code is executing when revoking a method?

  - by fayer

  to learn a library/framework i think the best way would be to use a class method and then see what code is executing in live. then you see the method chain (input and output of each) and can also read the comments. is there a such feature in any IDE or external application for php?

• How can I know whether an instance implements a method in Objective-C ?

  - by Thomas Joulin

  I would like to know if an instance implements a specific method. I could use respondsToSelector: but it returns YES if the instance inherits the method... I could loop through the methods of class_copyMethodList(), but since I might want to check a lot of instances, I wanted to know if there was a simpler solution (like repondsToSelector:, but restricted to the class itself...)

• Is there a method in java that can take 2 numbers and give you the numbers that are in between them(

  - by Zeroe

  I read in a file with a few numbers using a scanner, and then split them using the split method. My main issue is if there is a method that can just give me ranges, probably in the math class. The numbers are currently in an array, and I wanna move those numbers and there ranges into a two-dimensional array. Could anyone give me some tips or tricks to go about that?

• IEnumerator: Is it normal to have an empty Dispose method?

  - by C. Ross

  I'm writing an IEnumerator<T> class to iterate over a COM collection I'm wrappering. I've noticed that IEnumerator<T> extends IDisposable, so I'm required to implement the Dispose method. However, I can't think of anything I would put there, as I only have a reference to the collection (which I wouldn't want being disposed at the end of a foreach), and an int for the index. Is it normal to leave the Dispose method empty?

• Collection, which method is used to authorize an add of an element ?

  - by Duke Vador

  We find a lot of concrete subclasses under Collection. While trying to add an element in a concrete collection, this collection will use a method to determine if it can accept to store the element (and eventually that this element is not already in the collection). It could use equals(), hashCode() or compareTo() of the element. Is it possible to find a summary about which method is used by each implementation of Collection ? Thanks a lot for your answers.

• Not Possible to Reference self in a Method Declaration?

  - by phasetwenty

  I wanted to write a method with an argument that defaults to a member variable like so: def method(self, arg1=0, arg2=self.member): Apparently this is not allowed. Should I write it a different way, or perhaps use a value of arg2 to signal when to use a different value?

• How do I find where a ruby method is declared?

  - by Joe Fair

  I have a ruby method (deactivate!) that is on an activeRecord class. However, I can't seem to find where that method is declared. There have been numerous developers on this project, so it could be anywhere. There is a deactivate! on an unrelated class, but it doesn't seem to get called. Any ideas how to find all the superclasses for an instace, or where to find the code for deactivate!?
