- All Implemented Interfaces:
- java.util.Map
- public class StringMap
- extends java.util.AbstractMap
Map like class of Strings to Objects.
This String Map has been optimized for mapping small sets of
Strings where the most frequently accessed Strings have been put to
the map first.
It also has the benefit that it can look up entries by substring or
sections of char and byte arrays. This can prevent many String
objects from being created just to look up in the map.
