11 | * Created by: Helena Shih | |
12 | * | |
13 | * Modification History: | |
14 | * | |
15 | * Date Name Description | |
16 | * 2/5/97 aliu Modified createDefault to load collation data from | |
17 | * binary files when possible. Added related methods | |
18 | * createCollationFromFile, chopLocale, createPathName. | |
19 | * 2/11/97 aliu Added methods addToCache, findInCache, which implement | |
20 | * a Collation cache. Modified createDefault to look in | |
21 | * cache first, and also to store newly created Collation | |
22 | * objects in the cache. Modified to not use gLocPath. | |
23 | * 2/12/97 aliu Modified to create objects from RuleBasedCollator cache. | |
24 | * Moved cache out of Collation class. | |
25 | * 2/13/97 aliu Moved several methods out of this class and into | |
26 | * RuleBasedCollator, with modifications. Modified | |
27 | * createDefault() to call new RuleBasedCollator(Locale&) | |
28 | * constructor. General clean up and documentation. | |
29 | * 2/20/97 helena Added clone, operator==, operator!=, operator=, and copy | |
30 | * constructor. | |
31 | * 05/06/97 helena Added memory allocation error detection. | |
32 | * 05/08/97 helena Added createInstance(). | |
33 | * 6/20/97 helena Java class name change. | |
34 | * 04/23/99 stephen Removed EDecompositionMode, merged with | |
35 | * Normalizer::EMode | |
36 | * 11/23/9 srl Inlining of some critical functions | |
37 | * 01/29/01 synwee Modified into a C++ wrapper calling C APIs (ucol.h) | |
