Examples OneTime

OneTime example

OneTime

This example shows object-scoped one-time logging.

What it demonstrates

• Deriving from OneTimeOverrideGenerator
• Using LOGME_ONCE4THIS
• Printing a message only once per object instance

Notes

• This is useful for repetitive warnings that should appear once per object instead of once per call site.

Console output

2026-05-03 10:34:00:330 W Test::Method(): something went wrong!!!
