Can/Should i inherit from STL iterator to implement my own iterator class? If 开发者_运维问答no, why not?Short answer
I have two classes, the first that contains a vector and a get-method like this: std::vector<mytype> const& MyClassA::getvector(std::vector<mytype>::iterator &it)
I a开发者_开发百科m using Ruby on Rails 3.0.7 and I would like to set a class CONSTANT value. Since the .each_key method for a hash class seems to not return values as it makes a map method for array
Writing iterators for custom collections in Java is quite complicated, because instead of writing straight-forward code that provides one element after the other, you esse开发者_如何学Cntially have to
SITUATION: I have a TreeSet of custom Objects and I have also used a custom Comparator. I have created an iterator to use on this TreeSet.
I have a vector that defined like below vector<Field&g开发者_运维技巧t; m_vField; I fill the vector by this command:
I\'m trying to loop on containers(map, set,vector,list) 开发者_开发技巧and array the same way.
I know that the postfix versions of the increment/decrement operators will generally be optimised by the compiler for built-in types (i.e. no copy will be made), but is this the case for iterators?

I have a collection of objects. Objects are instance of the same class. I need to verify that the variable reviewed_object_name occurs in the object_name field of any object in the collection.
