class ara::diag::DiagSovdErrorDomain

use

The default constructor initializes an instance of the error domain ara::diag::DiagSovdErrorDomain [SWS_DM_01812] in accordance with AUTOSAR_AP_SWS_Diagnostics §8.51.3.2.1.1 “Default Constructor”. The function is declared as constexpr as well as noexcept and requires the inclusion of the header #include "ara/diag/diag_sovd_error_domain.h" [SWS_DM_01812].

Interaction and Call Context

In typical application scenarios, direct manual instantiation via this constructor should rarely be required, since the functional interface ara::diag::GetDiagSovdErrorDomain() already provides a reference to the global instance of the error domain [SWS_DM_01816]. Question Q-8c4b22173b01dce7 (open)

The class DiagSovdErrorDomain defines the error domain for SOVD and provides essential types and functions:

• Type aliases for error codes Errc [SWS_DM_01810] and exception handling Exception [SWS_DM_01811].
• Creation of error code instances via MakeErrorCode() [SWS_DM_01817].
• Name query via Name() [SWS_DM_01813] and text translation via Message() [SWS_DM_01814], as well as throwing exceptions via ThrowAsException() [SWS_DM_01815].

Error Handling and Concurrency

As a parameterless noexcept function, the constructor does not throw any exceptions. According to the specification, the call is exception-safe ("exception safe") and concurrently thread-safe ("thread-safe") [SWS_DM_01812]. No specific preconditions or error codes are defined for the constructor.

The member function Message of class ara::diag::DiagSovdErrorDomain serves to synchronously translate a numeric error code into a readable text message [SWS_DM_01814] (evidenced in AUTOSAR_AP_SWS_Diagnostics p. 69). It is provided via the header file ara/diag/diag_sovd_error_domain.h in namespace ara::diag.

The following specification characteristics apply to the call and runtime behavior:

• Usage and semantics: As an input parameter, errorCode of type ara::core::ErrorDomain::CodeType is passed. The function synchronously returns a pointer to a constant character string (const char *) that contains the textual error description. The specification bindingly guarantees that this return value is never nullptr [SWS_DM_01814].
• Error handling and robustness: The interface is qualified with noexcept and defined as exception safe (exception safe) [SWS_DM_01814]. No C++ exceptions are thrown. Interpretation: When passing an undefined or unknown error code, the implementation is likely to return a standardized informational message in order to fulfill the guarantee against null pointers. Question Q-c115f3da24bde8bd (open)
• Concurrency: The method is declared as a const operation and explicitly specified as thread-safe (thread-safe) [SWS_DM_01814]. It does not modify internal states, is subject to no sequencing constraints, and can be called in parallel from multiple threads without external locks or synchronization mechanisms.
• Interplay in Diagnostic Management: The method provides the standardized text translation for the SOVD error domain. It follows the uniform architecture pattern of the Adaptive Platform and corresponds in signature and behavior to the Message implementations of related diagnostic error domains such as DiagErrorDomain [SWS_DM_00522], DiagUdsNrcErrorDomain [SWS_DM_00534], DiagOfferErrorDomain [SWS_DM_00994], and DiagReportingErrorDomain [SWS_DM_01001].

use

The method Name of class ara::diag::DiagSovdErrorDomain returns the short name (ApApplicationErrorDomain.SN) of the SOVD error domain synchronously as a C string (const char*) ([SWS_DM_01813]; AUTOSAR_AP_SWS_Diagnostics §7 “Diagnostics”). The function expects no parameters and is provided via header ara/diag/diag_sovd_error_domain.h ([SWS_DM_01813]). Interpretation: The returned pointer is likely to point to an immutable, statically stored character string that remains valid throughout the entire runtime. Question Q-b7b74a09ea645e46 (open)

Error Handling and Concurrency

The function is declared as noexcept and considered exception safe (exception safe) ([SWS_DM_01813]). It reports no error codes and generates neither DET nor DEM entries. Regarding concurrency, the method is specified as thread-safe (thread-safe) ([SWS_DM_01813]). It thus possesses reentrant properties and can be called from arbitrary threads without external synchronization mechanisms.

Interaction

The interface follows the uniform name querying pattern for error domains in adaptive diagnostics. Corresponding implementations can be found in ara::diag::DiagErrorDomain ([SWS_DM_00521]), ara::diag::DiagUdsNrcErrorDomain ([SWS_DM_00533]), ara::diag::DiagOfferErrorDomain ([SWS_DM_00993]), and ara::diag::DiagReportingErrorDomain ([SWS_DM_01000]). It typically serves for logging and identifying error domains in the SOVD context.

use

The method ThrowAsException of class ara::diag::DiagSovdErrorDomain ([SWS_DM_01815], declared in header ara/diag/diag_sovd_error_domain.h; see AUTOSAR_AP_SWS_Diagnostics §8.51.3.2.2.3 “ThrowAsException”) serves to convert an error code synchronously into the assigned C++ exception type. It accepts the input parameter errorCode of type const ara::core::ErrorCode & and has no return value (void). When called, it throws the exception corresponding to the error code according to the signature with noexcept(false).

Error Handling and Boundary Conditions

The specification classifies the method as “not exception safe” ([SWS_DM_01815]). Interpretation: This classification is likely justified by the fact that throwing an exception intentionally leaves regular control flow. Question Q-23924e13760f4186 (open) A key constraint concerns the compiler toolchain: According to [SWS_CORE_10304], ThrowAsException does not participate in overload resolution if C++ exceptions are disabled in the compiler.

Concurrency and Interaction

The function is classified as thread-safe (thread-safe) ([SWS_DM_01815]) and allows concurrent calls. The behavior follows the standardized scheme for diagnostic error domains in module DM. Analogous definitions apply to ara::diag::DiagErrorDomain ([SWS_DM_00523], see AUTOSAR_AP_SWS_Diagnostics §8.11.3.2.2.3 “ThrowAsException”), ara::diag::DiagOfferErrorDomain ([SWS_DM_00995], see AUTOSAR_AP_SWS_Diagnostics §8.11.5.2.2.3 “ThrowAsException”), ara::diag::DiagReportingErrorDomain ([SWS_DM_01002], see AUTOSAR_AP_SWS_Diagnostics §8.11.7.2.2.3 “ThrowAsException”), and ara::diag::DiagUdsNrcErrorDomain ([SWS_DM_00535], see AUTOSAR_AP_SWS_Diagnostics §8.12.3.2.2.3 “ThrowAsException”).
