```
long getMaxAgeMillis()
```
    Returns the lifetime of the cache entry. This hint suggests to the cache that the entry will not be useful after the provided number of milliseconds passes, and suggests that the cache should discard the entry when this interval elapses even if it is not explicitly invalidated. Note that this time counts from the creation of the entry, not from last use.
    
    Returns:
    
    The lifetime of this entry, in milliseconds. If the lifetime is unknown or irrelevant, this will return Long.MAX_VALUE.
