Type Parameters:

S - source type

T - target type
```
public interface KeyBimap<S,T>
```
A bidirectional map between key types S and T (source and target). This is used to create adapters exposing a T→V cache as a S→V cache.
The S→T mapping must be injective. If the S→T mapping is not bijective, getSource(Object) should return null for target keys with no corresponding source key.
