BinaryStore.SizeAware (Oracle® Coherence Java API Reference)

All Superinterfaces:

BinaryStore

All Known Subinterfaces:

BinaryStore.KeySetAware

All Known Implementing Classes:

BinaryMapStore, JournalBinaryStore

Enclosing interface:

BinaryStore
```
public static interface BinaryStore.SizeAware
extends BinaryStore
```
If a BinaryStore is aware of the number of keys that it stores, then it should implement this optional interface in order to allow that information to be efficiently communicated to an intelligent consumer of the BinaryStore interface.
