Class SmallMap

java.lang.Object

java.util.AbstractMap

org.biojava.nbio.ontology.utils.SmallMap

All Implemented Interfaces:

java.io.Serializable, java.util.Map

public class SmallMap
extends java.util.AbstractMap
implements java.io.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.
