FormatSharedNamesAndAppendUniqueStringToThoseWhichRepeat (Apache jclouds 2.1.0 API)

java.lang.Object
- org.jclouds.compute.internal.FormatSharedNamesAndAppendUniqueStringToThoseWhichRepeat

All Implemented Interfaces:

GroupNamingConvention
```
public class FormatSharedNamesAndAppendUniqueStringToThoseWhichRepeat
extends Object
implements GroupNamingConvention
```
Get a name using a random mechanism that still ties all nodes in a group together. This implementation will pass the group and a hex formatted random number to the configured naming convention.
