Some of my colleagues p开发者_如何学JAVArefer to explicitly initialize std::auto_ptr to 0 in constructor initialization list, but it will be initialized to 0 in it\'s constructor without any explicit
I\'ve read a reasonable amount in decent textbooks about the aut开发者_开发知识库o_ptr class.While I understand what it is, and how it gets you around the problem of getting exceptions in places like
Suppose I want to write factory method that is supposed to allocate heterogeneous objects on the heap and return them to the caller. I am thinking of designing the API like this:
I\'ve got an abstract base class that defines an interface to data sinks.Concrete implementations of data sinks are acquired via factories.In an effort to tidy up code, I created a typedef for the fac
I ran this program but I didn\'t get what this auto_ptr does and 开发者_Go百科on which basics it shows the values?
Lets say I have heap allocated A*, which I want to pass as argument to boost::bind. boost::bind is saved for later processing in some STL like container of boost::functions\'s.
When trying to use an auto_ptr with a type that was declared with forward-declaration, like this: class A;
I have a assignment operator. AP<T>& operator=(AP<T>& o) {Super::operator=(o); return *this; }
Why operator [] is not allowed on std::auto_ptr?开发者_JS百科 #include <iostream> using namespace std ;
i have a function that does this: static MyClass* MyFunction(myparams) { return new MyClass(myparams) } and i would be able to call this function inside another one that has the following signature
