CLASS-METHODS - RETURNING

Syntax

CLASS-METHODS meth
[IMPORTING parameters] [PREFERRED PARAMETER p]]
RETURNING VALUE(r) typing
[{RAISING exc1|RESUMABLE(exc1) exc2|RESUMBALE(exc2) ...}
|{EXCEPTIONS exc1 exc2 ...}].

Effect

Declares a functional static method meth. The additions have exactly the same syntax and meaning as those for functional instance methods.

Example

The class circle contains two functional static methods, circumference and area, which work with the constant pi.

CLASS circle DEFINITION.
PUBLIC SECTION.
CONSTANTS pi TYPE decfloat34
VALUE '3.141592653589793238462643383279503'.
CLASS-METHODS: circumference IMPORTING r TYPE decfloat34
RETURNING value(c) TYPE decfloat34,
area IMPORTING r TYPE decfloat34
RETURNING value(a) TYPE decfloat34.
ENDCLASS.

CLASS circle IMPLEMENTATION.
METHOD circumference.
c = 2 * pi * r.
ENDMETHOD.
METHOD area.
a = pi * r ** 2.
ENDMETHOD.
ENDCLASS.

DATA: circ TYPE decfloat34,
area TYPE decfloat34,
radius TYPE decfloat34.

START-OF-SELECTION.

radius = '1.00'.
circ = circle=>circumference( radius ).
area = circle=>area( radius ).
