Class Fields NET

Class fields are data fields in a class that can be accessed without an object reference.

You can introduce a block of class fields within a class declaration by using the class var block declaration. All fields declared after class var have static storage attributes. A class var block is terminated by the following:

  1. Another class var declaration
  2. A procedure or function (i.e. method) declaration (including class procedures and class functions)
  3. A property declaration (including class properties)
  4. A constructor or destructor declaration
  5. A visibility scope specifier (public, private, protected, published, strict private, and strict protected) For example:

type

TMyClass = class public class var // Introduce a block of class static fields.

Red: Integer; Green: Integer; Blue: Integer;

procedure Proci; // Ends the class var block.

end;

The above class fields can be accessed with the code:

TMyClass.Red := 0; TMyClass.Green := 0; TMyClass.Blue := 0;
