Class SmallMap
java.lang.Object
java.util.AbstractMap
org.biojava.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.
