| 14 | * Private implementation header for C/C++ collation. | |
| 15 | * Some file data structure definitions were moved here from i18n/ucol_imp.h | |
| 16 | * so that the common library (via ucol_swp.cpp) need not depend on the i18n library at all. | |
| 17 | * | |
| 18 | * We do not want to move the collation swapper to the i18n library because | |
| 19 | * a) the resource bundle swapper depends on it and would have to move too, and | |
| 20 | * b) we might want to eventually implement runtime data swapping, | |
| 21 | * which might (or might not) be easier if all swappers are in the common library. | |
