| /** |
| * File coll.cpp |
| * |
| * Created by: Helena Shih |
| * |
| * Modification History: |
| * |
| * Date Name Description |
| * 2/5/97 aliu Modified createDefault to load collation data from |
| * binary files when possible. Added related methods |
| * createCollationFromFile, chopLocale, createPathName. |
| * 2/11/97 aliu Added methods addToCache, findInCache, which implement |
| * a Collation cache. Modified createDefault to look in |
| * cache first, and also to store newly created Collation |
| * objects in the cache. Modified to not use gLocPath. |
| * 2/12/97 aliu Modified to create objects from RuleBasedCollator cache. |
| * Moved cache out of Collation class. |
| * 2/13/97 aliu Moved several methods out of this class and into |
| * RuleBasedCollator, with modifications. Modified |
| * createDefault() to call new RuleBasedCollator(Locale&) |
| * constructor. General clean up and documentation. |
| * 2/20/97 helena Added clone, operator==, operator!=, operator=, and copy |
| * constructor. |
| * 05/06/97 helena Added memory allocation error detection. |
| * 05/08/97 helena Added createInstance(). |
| * 6/20/97 helena Java class name change. |
| * 04/23/99 stephen Removed EDecompositionMode, merged with |
| * Normalizer::EMode |
| * 11/23/9 srl Inlining of some critical functions |
| * 01/29/01 synwee Modified into a C++ wrapper calling C APIs (ucol.h) |
