Constant

```
public interface LocalAttribute.Constant

                    
```
Used for attributes that have a finite set of possible values (such as enumerations, see ViewScopeInstrumentationType). This interface makes it possible to use only the value (see enrichWithConstantAttribute) when setting an attribute and reduces the possibility of inconsistent use of api (when an unsupported value is passed for a particular attribute key).
