RegionTransition (Apache HBase 1.4.11 API)

java.lang.Object
- org.apache.hadoop.hbase.RegionTransition

```
@InterfaceAudience.Private
public class RegionTransition
extends Object
```
Current state of a region in transition. Holds state of a region as it moves through the steps that take it from offline to open, etc. Used by regionserver, master, and zk packages. Encapsulates protobuf serialization/deserialization so we don't leak generated pb outside this class. Create an instance using createRegionTransition(EventType, byte[], ServerName).
