/**
* Indicates a public API that is stable for callers to use, but has no guarantee of stability for
* extension. Consequently, the API should only be extended within the package containing the API.
*
* For example:
*
*
* - An interface marked with this annotation can have new methods added to it.
*
- A non-final class with this annotation can be marked final.
*
- A class with this annotation can have new abstract methods added.
*
- a non-final method with this annotation can be marked final.
*
*
* The list above is just for illustration purposes and is not exhaustive.
*
*
Adding this annotation to an API is considered API-breaking.
