RAII

May 18, 2012

RAII is Resource Acquisition Is Initialization, and it’s a neat concept once you understand what it means and how it’s used. RAII was born out of C++ and invented by its creator Bjarne Stroustrup.

In C++, the only code that can be guaranteed to be executed after an exception is thrown are the destructors of objects residing on the stack. Resource management needs to be tied to the lifespan of suitable objects in order to gain automatic allocation and reclamation. Resources are acquired during initialization, and guaranteed to be released with the destruction of the same objects.
