# Class-File API

Use for **Class-File API** work from [JEP 484](https://openjdk.org/jeps/484) when targeting JDK 24+.

## When active

- Use `ClassFile.of()` as the parse/build/transform entry point.
- Use models and builders instead of visitor boilerplate.
- Use transforms to pass through, drop, or replace class-file elements.

## Pitfalls

- This is not reflection over loaded classes.
- Do not manually manage constant pools, labels, or stack maps unless necessary.
- Final API differs from preview names.

## Examples

Read `examples/jep-484.md` for JEP-derived snippets.
