Annotation Interface TrackCaller

Javadoc 27 generates this reference during each site build from the exported packages and the annotation processor. The Java guide shows the API in use.

@Documented @Retention(RUNTIME) @Target(TYPE) public @interface TrackCaller

Marks a class as a layer over this package, such as a builder in another JVM language, whose frames call sites skip.

The call site of a statement is the innermost frame outside this package. Frames of a class that carries this annotation, or that a class carrying it encloses, are skipped too, so that a statement made through the layer points at the code that called the layer, as Rust's #[track_caller] does. A Kotlin file opts in with @file:TrackCaller.
