Everything about Destructor (computer programming)

Function called at the end of an object's lifetime

In object-oriented programming, a destructor is a method which is invoked mechanically just before the memory of the object is released. It can happen either when its lifetime is bound to scope and the execution leaves the scope, when it is embedded in another object whose lifetime ends, or when it was allocated dynamically and is released explicitly. Its main purpose is to free the resources which were acquired by the object during its life and/or deregister from other entities which may keep references to it. Destructors are necessary in resource acquisition is initialization (RAII). Wikipedia →
