ChangeEvent (CommonVox tools for HBase™ - ColumnManagerAPI for HBase™ 1.1.1-beta-04 API)

Object
- ChangeEvent

All Implemented Interfaces:

Comparable<ChangeEvent>
```
public class ChangeEvent
extends Object
implements Comparable<ChangeEvent>
```
A ChangeEvent (obtained via a ChangeEventMonitor's various get methods) contains metadata pertaining to a structural change made to a component of a ColumnManager-included Namespace, Table, or Table component; for example, a change to the "durability" setting of a Table or the "maxVersions" setting of a Column Family is captured in the ColumnManager repository as a ChangeEvent. When ColumnManager is activated, such ChangeEvents are comprehensively tracked in the ColumnManager repository for all Namespaces and Tables (and their components) that are included in ColumnManager processing.
