# Annotation Interface Experimental

@Inherited @Retention(RUNTIME) @Target({FIELD,TYPE}) public @interface Experimental
Annotation that specifies that an element is experimental and may change without notice.

Clients that visualize Flight Recorder events should not show the events or fields annotated with the `Experimental` annotation by default. This annotation allows event producers the freedom to try out new events without committing to them.

Clients may provide a check box (for example, in a preference page) where a user can opt-in to display experimental data. If the user decide to do so, the user interface should mark experimental events or fields so users can distinguish them from non-experimental events.

This annotation is inherited.
