* Description:
|
|
* This file contains dependencies that the collation run-time doesn't normally
|
|
* need. This mainly contains resource bundle usage and collation meta information
|
|
*
|
|
* Modification history
|
|
* Date Name Comments
|
|
* 1996-1999 various members of ICU team maintained C API for collation framework
|
|
* 02/16/2001 synwee Added internal method getPrevSpecialCE
|
|
* 03/01/2001 synwee Added maxexpansion functionality.
|
|
* 03/16/2001 weiv Collation framework is rewritten in C and made UCA compliant
|
|
* 12/08/2004 grhoten Split part of ucol.cpp into ucol_res.cpp
