Hi Experts,

I am new to Object orientedABAP.

Can any body tell me how to call a built-in class and method in to my ABAP report with some example?

You should simply look at one of the BCEDIT programs.

1. Create the object for the class

2. Call the method of the class using the object created. You can use the pattern button of the ABAP Editor.

Here is a example.

hi,

Tcode -> SE24. Give the class name cl_http_client->

Display. You will find a list of methods that are implemented in that class.

call method cl_http_client=>create_by_url

exporting

url = wf_string

importing

client = http_client

exceptions

argument_not_found = 1

plugin_not_active = 2

internal_error = 3

others = 4.

create_by_url is a STATIC method. So, we used => as operator. If we want to access INSTANCE methods, we have to use -> operator.

Sailaja.

go to pattern and choose ABAP object patterns.

Enter object name,method name and class name.

To call object

enter class name and object name.

Reward points if helpful.

Hi Thanks.

Points are given.

Whare to create object for the class?

After creating object for that calss we need to call that method by clicking Pattern button?

You can create the object/instance of the class in the program (report / dialog program) where you want to make that call. Even the CREATE OBJECT also can be done using the pattern

Once that is done use the instnace name and the class name to get the pattern of the method.

Hi Ravi,

In Object Oriented There is you 1st make local class define all the and then implement event in it than in PBO set handler. and the class is:

Classes describe objects. From a technical point of view, objects are runtime instances of a class. In theory, you can create any number of objects based on a single class. Each instance (object) of a class has a unique identity and its own set of values for its attributes.
