CLASS-METHODS - RETURNING

Short Reference

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

What does it do? This statement declares a functional
static method meth . The additions have exactly the same syntax and meaning as those for functional instance methods .

Example ABAP Coding The class circle contains two functional static methods, circumference and area , which work with the constant pi .
CLASS circle DEFINITION.
