• Can a trait state if a C++ class has a default constructor?

  - by Vicente Botet Escriba

  Traits classes can be defined to check if a C++ class has a member variable, function or a type (see here). Curiously, the ConceptTraits do not include traits to check if a C++ class defines a default constructor or given constructor? Can traits be used to check the constructor presence? If yes, how? If not, why it is not possible?

• How can I have a Foo* iterator to a vector of Foo?

  - by mghie

  If I have a class that contains a std::list<Foo>, how can I implement iterators to a Foo* collection, preferably without using boost? I'd rather not maintain a parallel collection of pointers. For now I have std::list<Foo>, mostly so that removing or inserting an element does not invalidate all other iterators, but would it be possible to implement other iterators too, so that the collection type used in the implementation is opaque to the user of the class?

• Difference between [object variable] and object.variable in Obj-C?

  - by John Smith

  I was working on a program today and hit this strange bug. I had a UIButton with an action assigned. The action was something like: -(void) someaction:(id) e { if ([e tag]==SOMETAG) { //dostuff } } What confuses me is that when I first wrote it, the if line was if (e.tag==SOMETAG) XCode refused to compile it, saying error: request for member 'tag' in 'e', which is of non-class type 'objc_object*' but I thought the two were equivalent. So under what circumstances are they not the same?

• What are the standard practices for throwing JavasScript Exceptions?

  - by T.R.

  w3schools says that exceptions can be strings, integers, booleans, or objects, but the example given doesn't strike me as good practice, since exception type checking is done through string comparison. Is this the preferred method of exception handling in JavaScript? Are there built-in exception types (like NullPointerException)? (if so, what are they, what kind of inheritance do they use, and are they preferred over other options?)

• What Are Collections Implemented As In VB6?

  - by Tom Tresansky

  So a collection in VB6 keeps track of a key for each object, and you can look up the object by its key. Does that mean collections are implemented as some sort of hashtable under the hood? I realize you can have multiple items with the same key in a collection, hence the SOME SORT. Anybody know what type data structure a VB6 collection is supposed to represent?
