SmallMap (biojava-legacy 1.9.5 API)

java.lang.Object
- java.util.AbstractMap
- - org.biojava.utils.SmallMap

All Implemented Interfaces:

Serializable, Map
```
public class SmallMap
extends AbstractMap
implements Serializable
```
Lightweight implementation of Map which uses little memory to store a small number of mappings, at the expense of scalability. Not recommended for more than 20-30 mappings.
This implementation has the useful property that the iteration order is the same as the order in which mappings are added.
