/**
 * Wrapper class for UErrorCode, with conversion operators for direct use
 * in ICU C and C++ APIs.
 * Intended to be used as a base class, where a subclass overrides
 * the handleFailure() function so that it throws an exception,
 * does an assert(), logs an error, etc.
 * This is not an abstract base class. This class can be used and instantiated
 * by itself, although it will be more useful when subclassed.
 *
 * Features:
 * - The constructor initializes the internal UErrorCode to U_ZERO_ERROR,
 *   removing one common source of errors.
 * - Same use in C APIs taking a UErrorCode * (pointer)
 *   and C++ taking UErrorCode & (reference) via conversion operators.
 * - Possible automatic checking for success when it goes out of scope.
 *
 * Note: For automatic checking for success in the destructor, a subclass
 * must implement such logic in its own destructor because the base class
 * destructor cannot call a subclass function (like handleFailure()).
 * The ErrorCode base class destructor does nothing.
 *
 * Note also: While it is possible for a destructor to throw an exception,
 * it is generally unsafe to do so. This means that in a subclass the destructor
 * and the handleFailure() function may need to take different actions.
 *
 * Sample code:
 * \code
 *   class IcuErrorCode: public icu::ErrorCode {
 *   public:
 *     virtual ~IcuErrorCode() {  // should be defined in .cpp as "key function"
 *       // Safe because our handleFailure() does not throw exceptions.
 *       if(isFailure()) { handleFailure(); }
 *     }
 *   protected:
 *     virtual void handleFailure() const {
 *       log_failure(u_errorName(errorCode));
 *       exit(errorCode);
 *     }
 *   };
 *   IcuErrorCode error_code;
 *   UConverter *cnv = ucnv_open("Shift-JIS", error_code);
 *   length = ucnv_fromUChars(dest, capacity, src, length, error_code);
 *   ucnv_close(cnv);
 *   // IcuErrorCode destructor checks for success.
 * \endcode
