CLASS-METHODS, RETURNING

Short Reference

CLASS-METHODS meth $[DEFAULT IGNORE$|FAIL$]
  $[IMPORTING parameters $[PREFERRED PARAMETER p$]$]
  $[EXPORTING parameters$]
  $[CHANGING  parameters$]
  RETURNING VALUE(r) typing
  $[${RAISING exc1$|RESUMABLE(exc1) exc2$|RESUMABLE(exc2) ...$}
  $|${EXCEPTIONS exc1 exc2 ...$}$].

Effect

This statement 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.




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 ).
