Internal Associated APIs

Class ErrorNoRegisterar

Error code registration class, for registering specific error codes and their description.

Includes the following member functions:

• Two constructors:

  ErrorNoRegisterar(uint32_t err, const std::string &desc) noexcept;

  ErrorNoRegisterar(const uint32_t err, const char *const desc) noexcept;

  where err indicates the error code and desc indicates the error code description.

• One default destructor:

  ~ErrorNoRegisterar() = default;

Class StatusFactory

Single-instance status factory class, for managing registered error codes.

Includes the following member functions:

• AscendString GetErrDescV2(const uint32_t err)

  for obtaining the error code description based on the error value. (This API is compatible with the ABI and is recommended.)

• static StatusFactory *Instance(),

  for returning an instance object of class StatusFactory, which must be unique.

• void RegisterErrorNo(uint32_t err, const std::string &desc)

  void RegisterErrorNo(const uint32_t err, const char *const desc)

  for registering error codes.

• std::string GetErrDesc(uint32_t err),

  for obtaining the error code description corresponding to a specific error code.
