Class 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.
