# Class 0F — Locator Exception

## Shared meaning {#meaning}

The first two characters `0F` identify `Locator Exception`. A locator value or locator operation is invalid. A class gives a directory-level family; each member still needs its own message, transaction aftermath, and response evidence.

## Members {#members}

The locked catalogue contains 2 members in this class:

[`0F000`](../../0f000/), [`0F001`](../../0f001/)

## Version boundary {#versions}

Member links lead to their own versioned facts; consult the version pages and source evidence for exact presence and change boundaries.

## Sources {#sources}

Members are generated from `data/classes.json` and the locked SQLSTATE directory.
