LookupCache (The Adobe Experience Manager SDK 2022.11.9850.20221116T162329Z-220900)

All Known Implementing Classes:

LRUMap
```
public interface LookupCache<K,V>
```
An interface describing the required API for the Jackson-databind Type cache.
Note that while interface itself does not specify synchronization requirements for implementations, specific use cases do. Typically implementations are expected to be thread-safe, that is, to handle synchronization.
