Answer»
- Classes are built to create objects and then the objects are allocated in the constructors and used in the METHODS.
- The objects that are allocated in the CONSTRUCTOR should have a releasing point and that is also in the destructor method.
- The process in which, the constructor constructs, and after the WORK destructor destructs is called CONVERSE process.
- The classes can be made to handle the memory properly by using the persistence property after the object that is currently used is being destroyed.
The example is as follows:
unit My;
interface
uses
Classes;
type
TMy = class
private
fileData : TStringList;
published
Constructor Create(CONST fileName : string);
Destructor Destroy; override;
procedure PrintFile;
end; The example is as follows: unit My;
interface
uses
Classes;
type
TMy = class
private
fileData : TStringList;
published
Constructor Create(const fileName : string);
Destructor Destroy; override;
procedure PrintFile;
end;
