Declare Constructor in PUBLIC SECTION

Overview

Declare Constructor in PUBLIC SECTION.

ATC Finding Message: Declare constructor in PUBLIC SECTION, even if class is CREATE PRIVATE

Rationale

Even when a class uses CREATE PRIVATE or CREATE PROTECTED, its instance constructor must be declared in the public section so the runtime and frameworks can instantiate it. Declaring the constructor privately makes reflection and framework integration harder. Keep the constructor in PUBLIC and control creation through the CREATE addition.

Non-Compliant

CLASS zcl_order_service DEFINITION PUBLIC CREATE PRIVATE.
  PRIVATE SECTION.
    METHODS constructor.
ENDCLASS.

Compliant

CLASS zcl_order_service DEFINITION PUBLIC CREATE PRIVATE.
  PUBLIC SECTION.
    METHODS constructor.
ENDCLASS.
