  - markNoValuesAndCheckAge
```
public abstract boolean markNoValuesAndCheckAge()
```
    Returns whether values should be stored due to max age. The caller should then call markValuesStored() after to let it know that values where stored.

```
    Evaluates the min age setting, holding the values as pending and returning a long indicting the nanoseconds until expiration, if applicable. If the return is <=0, the values can be stored.
