Member Method (VB.Net and Delphi Prism Cross Reference Guide)

Also known as a Class Method.

A code routine that belongs to the class or an object instance (an instance of the class). Methods that belong to the class are called class methods or static methods. Methods that belong to an object instance are called instance methods, or simply methods.

When a method returns a value, it is a function method. When no value is returned (or void), it is a procedure method.

Methods frequently use method parameters to transfer data. When one object instance calls another object instance using a method with parameters, you call that messaging.

VB.Net:   Sub, Function VB.Net�uses the keywords sub and function. A sub does not return a value and a function does. Many programmers like to use the optional call keyword when calling a sub to indicate the call is to a procedure. Syntax Example: Class definition: Public Class Cyborg � Inherits Object � Public Sub IntroduceYourself() ��� MessageBox.Show("Hi, I do not have a name yet.") � End Sub End Class Some event like a button click: Dim T1 As New Cyborg T1.IntroduceYourself()

Delphi Prism:   method, procedure, function Prism uses the keyword method for member methods and is the preferred syntax over the legacy procedure and function keywords. Although method is preferred, you can use procedure or function if you want the compiler to make sure all functions return a value and all procedures do not. Syntax Example: In the interface section: Cyborg = class(System.Object)   public method IntroduceYourself(); end; In the Implementation section: method Cyborg.IntroduceYourself(); begin   MessageBox.Show("Hi, I do not have a name yet."); end;  On some event like a button click: var T1: Cyborg; begin   T1 := New Cyborg;   T1.IntroduceYourself; end;
