interface ReferenceEntry<K,V>
An entry in a reference map.Entries in the map can be in the following states:
Valid:
- Live: valid key/value are set
- Loading: loading is pending
Invalid:
- Expired: time expired (key/value may still be set)
- Collected: key/value was partially collected, but not yet cleaned up
- Unset: marked as unset, awaiting cleanup or reuse
