Member Modifier (Delphi Prism and PHP Cross Reference Guide)

By Mike Prestwood

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

 
OOP Basics
 

Some languages support object-based concepts such as Paradox, Access, and VB Classic. Other languages have OO extensions and fully support object orientation in a hybrid fashion (such as C++ and Dephi for Win32). Finally, some lanages such as C#, VB.Net, Prism, and Java are entirely written in OO. Meaning, every line of code written must occur within a class).

Member Modifier

[Other Languages] 

Languages Focus

Traditional private, protected, public, etc. member modifiers are documented under the member visibility topic of the Cross Reference Encyclopedia. With member modifiers here, we address additional member modifiers such as method and field modifiers.

Delphi Prism:  "Member Modifiers"

Prism supports a full suite of member modifiers. Prism virtuality modifiers are virtual, override, final, and reintroduce.

Prism general modifiers are abstract, empty, async, external, locked, unsafe, implements, and iterator.

Not all member types support all member modifiers. For example, member fields support only readonly and implements.

Syntax Example:
Cyborg = public class(System.Object)
public
  method Speak(pMessage: String); virtual;
end;
 
Series888 = public class(Cyborg)
public
  method Speak(pMessage: String); override;
end;
