Inline a CAST helper that is only read once

Overview

Inline a CAST helper that is only read once.

ATC Finding Message: CAST helper is read exactly once in the next statement; inline it

Rationale

A CAST helper assigned to a temporary and read only once adds a variable that carries no extra meaning. Inlining the CAST into the consuming expression keeps the downcast and its use together. Use CAST type( ... )->method( ) when the helper is not reused.

Non-Compliant

DATA(lo_node) = CAST lcl_node( io_object ).
result = lo_node->get_tokens( ).

Compliant

result = CAST lcl_node( io_object )->get_tokens( ).

This rule provides an automated QuickFix directly in Eclipse ABAP Development Tools (ADT):

1. Position the cursor on the flagged statement.
2. Press Ctrl + 1 (Quick Assist).
3. Select the automated refactoring to apply the clean syntax immediately.

Suppression

" SAP CI_ prefix format:
... "#EC CI_INLINE_CAST
