| 2 * File: icuerrorcode.h | |
| 3 * Description: Wrapper class for UErrorCode, with conversion operators for | |
| 4 * direct use in ICU C and C++ APIs. | |
| 5 * Author: Fredrik Roubert | |
| 6 * Created: Thu July 4 2013 | |
| 7 * | |
| 8 * Features: | |
| 9 * - The constructor initializes the internal UErrorCode to U_ZERO_ERROR, | |
| 10 * removing one common source of errors. | |
| 11 * - Same use in C APIs taking a UErrorCode* (pointer) and C++ taking | |
| 12 * UErrorCode& (reference), via conversion operators. | |
| 13 * - Automatic checking for success when it goes out of scope. On failure, | |
| 14 * the destructor will log an error message and exit. | |
| 15 * | |
| 16 * Most of ICU will handle errors gracefully and provide sensible fallbacks. | |
| 17 * Using IcuErrorCode, it is therefore possible to write very compact code | |
| 18 * that does sensible things on failure and provides logging for debugging. | |
| 19 * | |
| 20 * Example: | |
| 21 * IcuErrorCode icuerrorcode; | |
| 22 * return collator.compareUTF8(a, b, icuerrorcode) == UCOL_EQUAL; | |
