org.apache.tomcat.util.collections.SimpleHashtable
This class implements a special purpose hashtable. It works like a normal java.util.Hashtable except that:
1. Keys to "get" are strings which are known to be interned, so that "==" is used instead of "String.equals". (Interning could be document-relative instead of global.)
2. It's not synchronized, since it's to be used only by one thread at a time.
3. The keys () enumerator allocates no memory, with live updates to the data disallowed.
4. It's got fewer bells and whistles: fixed threshold and load factor, no JDK 1.2 collection support, only keys can be enumerated, things can't be removed, simpler inheritance; more.
The overall result is that it's less expensive to use these in performance-critical locations, in terms both of CPU and memory, than java.util.Hashtable instances. In this package it makes a significant difference when normalizing attributes, which is done for each start-element construct. @version $Revision: 1.6 $
