Addition
Effect
This statement declares a functional
instance method meth The same applies to the additions ABSTRACT,
FINAL, DEFAULT, IMPORTING,
EXPORTING, CHANGING, RAISING, and EXCEPTIONS as to
general instance methods.
A functional method can be called as a function in a suitable reader position.
Addition
... RETURNING VALUE(r) typing
Effect
Alongside any other formal parameters, a functional method has precisely one return value r
declared using the addition RETURNING. The return value must be passed by
value using VALUE and be fully typed using typing. In the typing check,
special rules apply, depending on whether an
explicit actual parameter is bound with RECEIVING or the functional method is used in an operand position.
Notes
- In functional method calls, a functional method obscures a predefined function with the same name. This case can occur only in the methods of the class of the functional method; however, a method should never have the same name as a predefined function.
- Functional methods are allowed as actual parameters of methods, which enables the option of nesting method calls in an operand position.
-
Within a method, the predicate
expression
IS SUPPLIEDcan be used to check whether an actual parameter was assigned to the return value when the call was made. This is always the case in functional method calls.
