Constructors in SAP ABAP
A constructor, as a special method within a class in SAP ABAP, triggers automatically upon creation of an object. In essence, a constructor is responsible for allocating memory space for an object; it sets initial values–either user-defined or system defaults–to instance variables within that object.
Role of Constructors in SAP ABAP:
Constructors primarily undertake the essential setup or initialization tasks upon object instantiation. They initialize the attributes of an object to either default values, or values passed during its creation as parameters. By ensuring proper configuration and readiness for use, constructors avert any subsequent operations from yielding unexpected behavior or errors.
Triggering Constructors in SAP ABAP:
In SAP ABAP, constructors are automatically triggered when an object is instantiated using the CREATE OBJECT statement.
DATA: obj TYPE REF TO <class_name>.
CREATE OBJECT obj.
- <class_name>: ame of the class.
- obj: object instance of the class being created.
Classes in SAP ABAP
SAP ABAP (Advanced Business Application Programming) is a high-level programming language created by the German software company SAP SE. ABAP is primarily used for developing and customizing applications within the SAP ecosystem, which includes enterprise resource planning (ERP) systems and other business software solutions. C++ is used to implement the ABAP kernel. A procedural and object-oriented programming model are both supported by the hybrid programming language ABAP.
