SimpleEnumeratingScheme (ELKI: Environment for DeveLoping KDD-Applications Supported by Index-Structures)

java.lang.Object
- elki.result.textwriter.naming.SimpleEnumeratingScheme

All Implemented Interfaces:

NamingScheme
```
public class SimpleEnumeratingScheme
extends java.lang.Object
implements NamingScheme
```
Simple enumerating naming scheme. Cluster names are generated as follows:
1. if the cluster has a name assigned, use it
2. otherwise use getNameAutomatic() as name, and add an enumeration postfix
Since:
