HostHistory

java.lang.Object
- google.registry.model.ImmutableObject

All Implemented Interfaces:

Buildable, UnsafeSerializable, java.io.Serializable, java.lang.Cloneable
```
@Entity
public class HostHistory
extends HistoryEntry
```
A persisted history entry representing an EPP modification to a host.
In addition to the general history fields (e.g. action time, registrar ID) we also persist a copy of the host entity at this point in time. We persist a raw HostBase so that the foreign-keyed fields in that class can refer to this object.
