Library containing caching functionality used by Digipost projects.

## Feature overview

### In-memory cache

The entry point for creating in-memory caches can be found in the

`no.digipost.cache2.inmemory` package, which wraps the

[Caffeine](https://github.com/ben-manes/caffeine) cache implementation.

In addition to standard key-value cache, this library also offers a

specialized API for caching a shared single object

([```SingleCached```](src/main/java/no/digipost/cache2/inmemory/SingleCached.java)).

### Fallback

Digipost Cache also supports a fallback-concept, currently implemented as

storing cache values on the file system. In the event of a cache value

[```Loader```](src/main/java/no/digipost/cache2/loader/Loader.java)

failing (e.g. if it resolves the value over the network or other error-prone I/O),

the last value it successfully loaded will instead be read from a disk-file.

Other ways to store and read values for fallback can be implemented by implementing

[```FallbackKeeper```](src/main/java/no/digipost/cache2/fallback/FallbackKeeper.java)

for storing a value for fallback, and the already mentioned ```Loader``` for

loading an already stored fallback value.
