| | 16 | * Private implementation header for C/C++ collation. |
| | 17 | * Some file data structure definitions were moved here from i18n/ucol_imp.h |
| | 18 | * so that the common library (via ucol_swp.cpp) need not depend on the i18n library at all. |
| | 19 | * |
| | 20 | * We do not want to move the collation swapper to the i18n library because |
| | 21 | * a) the resource bundle swapper depends on it and would have to move too, and |
| | 22 | * b) we might want to eventually implement runtime data swapping, |
| | 23 | * which might (or might not) be easier if all swappers are in the common library. |
