Self Keyword (Delphi and Delphi Prism Cross Reference Guide)

By Mike Prestwood

Delphi versus Delphi Prism: A side by side comparison between Delphi and Delphi Prism.

 
Language Details
 

Language Details is kind of a catch all for stuff that didn't make it into language basics nor any other category.

Self Keyword

[Other Languages] 
Delphi:   Self

Within the implementation of a method, the identifier Self references the object in which the method is called. The Self variable is an implicit parameter for each object method. A method can use this variable to refer to its owning class.

Syntax Example:
ShowMessage('Self=' + Self.ClassName);
Delphi Prism:   Self

Within the implementation of a method, the identifier Self references the object in which the method is called. The Self variable is an implicit parameter for each object method. A method can use this variable to refer to its owning class.

To refer to the current instance of a class or structure, use the Self keyword. It provides a way to refer to the specific instance in which the code is currently executing. It is particularly useful for passing information about the currently executing instance.

You cannot use it with static method functions because static methods do not belong to an object instance. If you try, you'll get an error.
