Everything about Resource acquisition is initialization

Approach to managing resources by tying them to object lifetime

Resource acquisition is initialization (RAII) is a programming idiom used in several object-oriented, statically typed programming languages to describe a particular language behavior. In RAII, holding a resource is a class invariant, and is tied to object lifetime. Resource allocation is done during object creation, by the constructor, while resource deallocation (release) is done during object destruction, by the destructor. In other words, resource acquisition must succeed for initialization to succeed. Thus, the resource is guaranteed to be held between when initialization finishes and finalization starts, and to be held only when the object is alive. Thus, if there are no object leaks, there are no resource leaks. Wikipedia →
