OO Object: Constructor and Static Attribute?

Former Member — Wed, 02 Apr 2008 19:25:58 GMT

I've defined an internal table to my Class as a static attribute. I would like it to be filled once during runtime and it should stay populated because it is a static attribute....right?

Please confirm: I need to create a method "Constructor". Within this method, it should load the internal table. This will occur when I say "Create Object" in my code automatically?

Am I correct?

Thank-You.

Hello,

You need to create the CLASS_CONSTRUCTOR method to populate the static internal table. This method run in the first time you use the create object or when you call a static method. And this method run only once per class.

The CONSTRUCTOR method is called every time you create a new instance to the class using the command CREATE OBJECT.

So, the CLASS_CONSTRUCTOR run only once, instead the times that the class is instancied and the CONSTRUCTOR run one time per instance.

Regards,

Justa adding a bit more information about CLASS_CONSTRUCTOR :

They are executed once per program

They are first executed when : -Create an instance of the class or

-Acessing a static attribute of the class

-Calling a static methid of the class

-Register and event for this class
