All Implemented Interfaces:

java.io.Serializable, RevisionHandler

Enclosing class:

LBR
```
public class LBR.Indexes
extends java.lang.Object
implements java.io.Serializable, RevisionHandler
```
Class for handling instances and the associated attributes.
Enables a set of indexes to a given dataset to be created and used with an algorithm. This reduces the memory overheads and time required when manipulating and referencing Instances and their Attributes.
