Instance vs Static Method

Former Member — Wed, 19 Nov 2008 15:28:07 GMT

I am trying to create a BADI Definition in the Enhancement Spot.

When I am creating a method in the BADI interface; I have the option of INSTANCE and STATIC.

Please elaborate the difference between the two; giving examples.

it's an elementary concept of object-oriented programming languages, please look at books or lots of threads in the forum.

briefly, you may call instance methods only on instances:

data instance_name type ref to class_name.
create object instance_name...
call method instance_name->instance_method( ... )

you may call static methods (also called class methods) only on class, does not need an instance

call method class_name=>static_method( ... )

Hi,

Instance methods are called using the following syntax:

CALL METHOD instance_name->instance_method_name.

A static method which is also called as class method can be called using the class and does not require an Instance. Static methods are called using the following syntax:

CALL METHOD class_name=>instance_method_name
