A destructor is a class routine that cleans up an object once a program finishes using that object. As for constructors, HLA does not provide a special syntax for creating destructors, nor does HLA automatically call a destructor. Unlike constructors, a destructor is usually a method rather than a procedure (because virtual destructors make a lot of sense, whereas virtual constructors do not). A typical destructor might close any files opened by the object, free the memory allocated during the use of the object, and, finally, free the object itself if it was created dynamically. The destructor also handles any cleanup chores the object may require before it ceases to exist. By convention, most HLA programmers name their destructors destroy. About the only code that most destructors have in common is the code to free the storage associated with the object. The following destructor demonstrates how to do this: other
