Protected components can be used by the superclass and all of the subclasses.
When we are talking subclassing and enheritance there is one more component than Public and Private, the Protected component. The static constructor cannot be called explicitly. Registering an evetm handler method for a static event The static constructor is always called CLASS_CONSTRUCTER, and is called autmatically before the clas is first accessed, that is before any of the following actions are executed:Ĭalling a ststic attribute using CALL METHOD
You must pass all non-optional parameters when creating an object. An instance constructor can have IMPORTING parameters and exceptions.
However, to implement a constructor you must declare it explicitly with the METHODS or CLASS-METHODS statements. The instance constructor is executed each time you create an object (instance) with the CREATE OBJECT statement, while the class constructor is executed exactly once before you first access a class. Implicitly, each class has an instance constructor method with the reserved name constructor and a static constructor method with the reserved name class_constructor. They are placed in the PRIVATE section of the class. METHODS: set_attributes IMPORTING p_name(25) TYPE c,Ĭan only be called from inside the class. Static attributes are defined with the keyword CLASS-DATA. The data are the same for all instances of the class, and can be used e.g. Static attributes exist only once for each class. Instance attributes are declared with the DATA keyword. There exist one instance attribute for each instance of the class, thus they exist seperately for each object. There is no direct access from outside the class. The can only be viewes and changed from within the class. Private attributes are defined in the PRIVATE section. As a general rule, as few public attributes should be defined as possible. There is direct access to public attributes.

In the above code I used DESERIALIZE( ) method of class /UI2/CL_JSON to deserialize JSON data. If you run the program, the json data will be displayed in an internal table ĪSSIGN COMPONENT `STARSHIP_CLASS` OF STRUCTURE TO. ĪSSIGN COMPONENT `MANUFACTURER` OF STRUCTURE TO. ĪSSIGN COMPONENT `MODEL` OF STRUCTURE TO. Pretty_name = /ui2/cl_json=>pretty_mode-userĪSSIGN COMPONENT `RESULTS` OF STRUCTURE TO. Lv_json_data = li_client->response->get_cdata( ). WRITE: / lv_url, ': OK', icon_checked AS ICON. SPLIT lv_error_message AT cl_abap_char_utilities=>newline INTO TABLE lt_errors. MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4. You can follow this and apply the logic to any REST API service provided by Azure, GCP and AWS.īelow is sample ABAP code to convert JSON data into ABAP internal table.
