SAP OO ABAP Training Introduction

One object can interact with another by accessing its attributes directly in a method, calling methods or triggering . An event Classes consist of source code containing the definition of possible objects. An object is always an instance of a class, which is addressed by at least one reference variable. All components and properties of its objects are declared in a class. The basis for encapsulation in ABAP Objects is always the class, rather than the object-1 Classes are either global for all programs or local in a single program. They can be specialized by inheritance and can incorporate standalone interfaces as a public interface. Attributes describe the status of an object. Technically speaking, attributes (instance attributes) are the local variables of an object, which cannot normally be changed directly from the outside. A class may also contain static attributes, which are jointly used by all objects of the class.Static attributes may be variables or constants. Methods allow objects to perform operations.

Instance method always works in a specific object. In other words, it reads and changes the status of this object and interacts with other objects by calling their methods or by triggering events. A method has a parameter interface and can pass on exceptions. A class may also contain static methods, which only accessstatic attributes and can trigger static events only.
