State (Apache Karaf :: Features :: Core 4.3.4 API)

java.lang.Object
- org.apache.karaf.features.internal.service.State

```
public class State
extends Object
```
Representation of the state of features service from the point of view of logical requirements which are translated into bundles and features installed in regions. It's a collection of:
- used repositories
- region -> requirements (logical feature requirements)
- region -> installed features (actual features installed - including conditionals and dependant features)
- region -> installed features -> state of feature installation
- region -> bundle ids (for bundles installed via features service, a.k.a. managed bundles)
- bundle id -> checksum
State is replaced (swapped) after uninstalling/updating/installing all the bundles as requested, but before resolving/refreshing them. Before State is set, work is done on the instance of Deployer.DeploymentState.
