In object-oriented programming, a destructor (sometimes
shortened to dtor) is a method which is automatically
invoked when the object is destroyed. Its main purpose is
to clean up and to free the resources which were acquired
by the object along its life cycle and unlink it from other
objects or resources invalidating any references in the
process. The use of destructors is key to the concept of
Resource Acquisition Is Initialization.
