A class can define a special method called its destructor, which always executes when an instance of the class is deleted (destroyed). ABL allows you to define one destructor as a named block that always begins with the DESTRUCTOR statement and always ends with the END DESTRUCTOR statement. This destructor must have the same name as the name of the class in which it is defined. The destructor is always PUBLIC, takes no parameters, and has no return type.
