What does it do? The statement METHODS declares or redefines an instance method meth. For the name meth, the naming conventions apply.
Instance methods are bound to objects. To use instance methods, an object of the class must first be created. In instance methods, all components of the same class can be accessed without a component selector.
Use the variants of statement METHODS to distinguish between the following kinds of method declarations: General Instance Methods The general form of the METHODS statement allows the definition of instance methods with any input and output parameters. Functional Instance Methods Functional methods have exactly one return value and any number of formal parameters. Instance Constructors Instance constructors are methods with the given name constructor , which are called automatically when their class is instantiated. Constructors have any number of input parameters and no output pa rameters. Event Handlers Event handlers are methods that, although they can be called directly with or in statements, are mainly called when an event of a class or an interface is triggered. The only possible formal parameters of an event handler are input parameters, which have been defined as the output parameters of the event. Redefinition of Instance Methods A method declared in a superclass can be redefined in a subclass as long as it is not flagged as final in the superclass. In a redefinition, the interface of the method is not changed. Definition of a Test Method Test methods can be declared in test classes. They have no interface parameters and are called during ABAP Unit tests by the ABAP runtime environment.
