किसी मौजूदा ऑब्जेक्ट के संदर्भ या उत्पन्न त्रुटि कोड की त्रुटि-सहिष्णु वापसी के लिए कार्य करता है।

विशिष्टीकरण ara::core::Result<T&, E> या तो प्रकार T& ([SWS_CORE_00902]) के सफल ऑपरेशन परिणाम के गैर-स्वामित्व वाले संदर्भ को या प्रकार E के उत्पन्न त्रुटि कोड को एनकैप्सुलेट करता है। उपयोगकर्ता संदर्भ-मुक्त करने वाले ऑपरेटरों या Value() के माध्यम से संदर्भित लक्षित ऑब्जेक्ट तक पहुँचने से पहले आम तौर पर HasValue() ([SWS_CORE_00918]) के माध्यम से किसी मान की उपस्थिति की जांच करते हैं। चूंकि इंस्टेंस संदर्भित ऑब्जेक्ट का स्वयं स्वामी नहीं है, इसलिए कॉलर को यह सुनिश्चित करने की आवश्यकता हो सकती है कि यह परिणाम के संपूर्ण उपयोग अवधि के दौरान मेमोरी में मान्य रहे। प्रश्न Q-48d71186fb35af77 (खुला)

संदर्भ

टेम्पलेट विशिष्टीकरण ara::core::Result<T&, E> या तो प्रकार value_type ([SWS_CORE_00902]) के सफल ऑपरेशन परिणाम के संदर्भ को या प्रकार error_type ([SWS_CORE_00903]) के त्रुटि मान को एनकैप्सुलेट करता है। मॉड्यूल core में एक मानकीकृत वापसी संरचना के रूप में, यह नियमित संचालन में C++ अपवादों के अनिवार्य उपयोग के बिना त्रुटि-मजबूत प्रोग्रामिंग को सक्षम बनाता है। विनिर्देश के अनुसार, कार्यान्वयन संकलन समय पर बाध्य करता है कि त्रुटि प्रकार E प्रकार ara::core::ErrorCode से मेल खाए; एक भिन्न असाइनमेंट संकलन त्रुटि की ओर ले जाता है। इंटरैक्शन भागीदारों में डेटा प्रदान करने वाली सेवाएं, परिणाम सत्यापन के लिए कॉलिंग घटक और बाहरी रूप से प्रबंधित लक्षित ऑब्जेक्ट शामिल हैं, जिसे बाउंड संदर्भ के माध्यम से सीधे एक्सेस किया जाता है।

जीवनचक्र

एक इंस्टेंस को या तो किसी मौजूदा lvalue के संदर्भ के साथ या किसी त्रुटि के साथ नियतात्मक रूप से आरंभ किया जाता है। संदर्भ के साथ आरंभीकरण कंस्ट्रक्टर [SWS_CORE_00908] या स्थैतिक फ़ैक्टरी विधि FromValue [SWS_CORE_00904] के माध्यम से होता है; rvalues पास करना अस्वीकार्य है। त्रुटि स्थितियाँ कंस्ट्रक्टरों ([SWS_CORE_00909], [SWS_CORE_00910]) या फ़ैक्टरियों जैसे FromError ([SWS_CORE_00905], [SWS_CORE_00906], [SWS_CORE_00907]) के माध्यम से उत्पन्न होती हैं। कोई मानक कंस्ट्रक्टर मौजूद नहीं है। कॉपी और मूव कंस्ट्रक्टर ([SWS_CORE_00911], [SWS_CORE_00912]) किसी अन्य इंस्टेंस की वर्तमान स्थिति को ग्रहण करते हैं।

स्वामित्व संबंधों के संदर्भ में, Result<T&, E> केवल एक संदर्भ को बांधता है और संदर्भित लक्ष्य ऑब्जेक्ट के लिए कोई स्वामित्व या जीवनकाल प्रबंधन ग्रहण नहीं करता है। इसलिए कॉलर को यह सुनिश्चित करना पड़ सकता है कि लक्ष्य ऑब्जेक्ट Result इंस्टेंस के संपूर्ण अस्तित्व के दौरान वैध बना रहे। प्रश्न (खुला) रनटाइम के दौरान स्थिति परिवर्तन असाइनमेंट ऑपरेटरों ([SWS_CORE_00914], [SWS_CORE_00915]) के माध्यम से किए जाते हैं, जो आंतरिक संदर्भ को नए लक्ष्य पर पुनः बांधते हैं या कोई त्रुटि स्थानांतरित करते हैं। इसके अलावा, EmplaceError [SWS_CORE_00916] इंस्टेंस को सीधे त्रुटि स्थिति में रखता है, जबकि Swap [SWS_CORE_00917] दो इंस्टेंसों की सामग्री का आदान-प्रदान करता है। डिस्ट्रक्टर [SWS_CORE_00913] सामान्य रूप से व्यवहार करता है, बशर्ते E मामूली रूप से विनिष्ट करने योग्य हो। मान या त्रुटि के समानांतर रीड एक्सेस थ्रेड-सुरक्षित हैं, जबकि स्थिति-परिवर्तनकारी संचालन जैसे असाइनमेंट, Swap या EmplaceError थ्रेड-सुरक्षित नहीं हैं।

उपयोग पथ

नियमित प्रक्रिया में स्थिति नियंत्रण और लक्षित मूल्यांकन शामिल है:

  • स्थिति जांच: एक्सेस से पहले, कॉलर HasValue() [SWS_CORE_00918] या रूपांतरण ऑपरेटर operator bool [SWS_CORE_00919] के माध्यम से जाँच करता है कि कोई मान मौजूद है या नहीं।
  • सीधा एक्सेस: सफलता की स्थिति में, Value() ([SWS_CORE_00924], [SWS_CORE_00925]), operator* ([SWS_CORE_00920], [SWS_CORE_00921]) और operator-> ([SWS_CORE_00922], [SWS_CORE_00923]) लक्ष्य ऑब्जेक्ट का संदर्भ या पॉइंटर प्रदान करते हैं।
  • वैकल्पिक और फ़ॉलबैक-आधारित एक्सेस: Ok() ([SWS_CORE_00926], [SWS_CORE_00927]) के माध्यम से संदर्भ को ara::core::Optional में परिवर्तित किया जा सकता है। विधि ValueOr() ([SWS_CORE_00933], [SWS_CORE_00934]) संदर्भित मान की एक प्रति या पास किया गया प्रतिस्थापन मान लौटाती है।
  • मोनाडिक संचालन: Bind() [SWS_CORE_00941] के साथ संदर्भ पर एक रूपांतरण फ़ंक्शन लागू किया जाता है और परिणाम को पैक किया जाता है, जबकि त्रुटियाँ स्वचालित रूप से अग्रेषित की जाती हैं। त्रुटि की स्थिति में Resolve() ([SWS_CORE_00939], [SWS_CORE_00940]) एक फ़ॉलबैक फ़ंक्शन को कॉल करता है जो एक संगत संदर्भ प्रदान करता है।

त्रुटि परिदृश्य

यदि इंस्टेंस त्रुटि स्थिति में है, तो Error() ([SWS_CORE_00928], [SWS_CORE_00929], [SWS_CORE_00930]) के ओवरलोड त्रुटि ऑब्जेक्ट तक पहुंच प्रदान करते हैं। इसके अतिरिक्त, त्रुटि को Err() ([SWS_CORE_00931], [SWS_CORE_00932]) के माध्यम से Optional<E> के रूप में या ErrorOr() ([SWS_CORE_00935], [SWS_CORE_00936]) के माध्यम से फ़ॉलबैक मान के साथ प्राप्त किया जा सकता है। विशिष्ट त्रुटि तुलनाओं के लिए, CheckError() [SWS_CORE_00937] निहित त्रुटि की तुलना एक संदर्भ त्रुटि से करता है।

विनिर्देश तत्व एक्सेस के लिए सख्त पूर्वशर्तों को परिभाषित करता है:

  • ResultWithNoValueViolation: बिना मान वाले इंस्टेंस पर Value() ([SWS_CORE_00924], [SWS_CORE_00925]), operator* ([SWS_CORE_00920], [SWS_CORE_00921]) या operator-> ([SWS_CORE_00922], [SWS_CORE_00923]) का कॉल एक विनिर्देश उल्लंघन का गठन करता है।
  • ResultWithNoErrorViolation: मान की उपस्थिति में Error() ([SWS_CORE_00928], [SWS_CORE_00929], [SWS_CORE_00930]) का एक्सेस पूर्व-शर्तों का उल्लंघन करता है।
  • अपवाद प्रबंधन: ValueOrThrow() ([SWS_CORE_00938], [SWS_CORE_00949]) कॉल त्रुटि होने पर त्रुटि से संबद्ध अपवाद थ्रो करते हैं; वे केवल तभी ओवरलोड रिज़ॉल्यूशन में भाग लेते हैं जब कंपाइलर में C++ अपवाद सक्षम हों।

उपयोग

सदस्य फ़ंक्शन const T * operator-> () const noexcept एक ara::core::Result<T &, E>-ऑब्जेक्ट [SWS_CORE_00922] के संदर्भित मान तक समकालिक पढ़ने की पहुँच प्रदान करता है। यह कोई तर्क नहीं लेता है और संदर्भित लक्ष्य ऑब्जेक्ट [SWS_CORE_00922] के लिए एक स्थिर सूचक (const T *) रिटर्न मान के रूप में प्रदान करता है। उपयोग के लिए, हेडर #include "ara/core/result.h" शामिल किया जाना चाहिए [SWS_CORE_00922]।

त्रुटि प्रबंधन

ऑपरेशन को noexcept के रूप में घोषित किया गया है और इसमें exception safe गुणधर्म है [SWS_CORE_00922]। यदि ऑब्जेक्ट में कोई मान नहीं है, तो पूर्व-शर्त का उल्लंघन (Violation) ResultWithNoValue होता है [SWS_CORE_00922]। इसलिए कॉल करने वालों को डीरेफरेंसिंग से पहले यह सुनिश्चित करना होगा कि इंस्टेंस वास्तव में एक मान्य मान रखता है।

समवर्तीता और प्रतिबंध

फ़ंक्शन को thread-safe निर्दिष्ट किया गया है [SWS_CORE_00922]। चूंकि यह एक स्थिर सदस्य फ़ंक्शन है, इसलिए एक ही इंस्टेंस पर समानांतर पठन सुरक्षित है। हालांकि, स्वयं लक्ष्य ऑब्जेक्ट तक पहुंच प्रकार T की थ्रेड-सुरक्षा गारंटियों के अधीन है।

इंटरैक्शन

यह ऑपरेटर गैर-स्थिर ओवरलोड T * operator-> () noexcept [SWS_CORE_00923] का स्थिर समकक्ष बनाता है। जबकि गैर-स्थिर संस्करण एक परिवर्तनीय पॉइंटर T* लौटाता है [SWS_CORE_00923], यह संस्करण संदर्भित इंस्टेंस तक अपरिवर्तनीय पहुँच को लागू करता है।

उपयोग

सदस्य फ़ंक्शन operator-> [SWS_CORE_00923] के अनुसार ara::core::Result<T&, E> के एक इंस्टेंस के संदर्भित मान तक सीधी पहुँच प्रदान करता है। फ़ंक्शन को हेडर फ़ाइल #include "ara/core/result.h" की आवश्यकता होती है, यह कोई पैरामीटर नहीं लेता है और समाहित या संदर्भित मान के लिए प्रकार T* का एक पॉइंटर लौटाता है। कॉल समकालिक रूप से निष्पादित होता है और इसे noexcept के साथ घोषित किया गया है।

त्रुटि प्रबंधन और सीमा शर्तें

यदि एक्सेस के समय ऑब्जेक्ट में कोई मान नहीं है, तो ResultWithNoValue-Violation के रूप में विनिर्देश का उल्लंघन होता है [SWS_CORE_00923]। इस सदस्य फ़ंक्शन के लिए कोई विशिष्ट DET या DEM त्रुटि संदेश निर्दिष्ट नहीं हैं। समवर्तीता और दोष सहिष्णुता के संबंध में, ऑपरेटर को thread-safe और साथ ही exception safe के रूप में वर्गीकृत किया गया है [SWS_CORE_00923]। कॉल करने वालों को उल्लंघन को रोकने के लिए संभवतः कॉल से पहले यह सुनिश्चित करना चाहिए कि इंस्टेंस वास्तव में एक मान्य मान रखता है। प्रश्न Q-a4b13cd34a40eb19 (खुला)

template <typename F> auto Bind (F &&f) const -> <see below>;

Apply the given Callable to the value of this instance, and return a new Result with the result of the call. The Callable is expected to be compatible to one of these two interfaces: • Result<XXX, E> f(const T&); • XXX f(const T&); meaning that the Callable either returns a Result<XXX> or a XXX directly, where XXX can be any type that is suitable for use by class Result. The return type of this function is decltype(f(Value())) for a template argument F that returns a Result type, and it is Result<decltype(f(Value())), E> for a template argument F that does not return a Result type.

फ़ंक्शन ValueOrThrow [SWS_CORE_00938] Upstream: RS_AP_00130

const T & ValueOrThrow () const noexcept(false);

Return the contained value or throw an exception.

टेम्पलेट विशेषज्ञता ara::core::Result<T &, E> का सिंक्रोनस मेंबर फ़ंक्शन ValueOrThrow शामिल मान ([SWS_CORE_00938]) तक पहुंच को सक्षम बनाता है। सफल ऑपरेशन पर, यह समाहित संदर्भ लक्ष्य के लिए एक कॉन्स्टेंट संदर्भ (const T &) लौटाता है।

यदि ऑब्जेक्ट किसी त्रुटि स्थिति का प्रतिनिधित्व करता है, तो फ़ंक्शन विशिष्ट त्रुटि से जुड़ा अपवाद (noexcept(false)) थ्रो करता है ([SWS_CORE_00938])। विनिर्देश ऑपरेशन की अपवाद सुरक्षा को स्पष्ट रूप से अपवाद-सुरक्षित नहीं (not exception safe) के रूप में वर्गीकृत करता है ([SWS_CORE_00938])।

समवर्तीता के संबंध में, मेथड को थ्रेड-सुरक्षित घोषित किया गया है ([SWS_CORE_00938])। एक महत्वपूर्ण सीमा शर्त बिल्ड कॉन्फ़िगरेशन से संबंधित है: यदि कंपाइलर टूलचेन में C++ अपवाद अक्षम हैं, तो ValueOrThrow ओवरलोड रिज़ॉल्यूशन में भाग नहीं लेता है ([SWS_CORE_00938])।

हेडर ara/core/result.h के भीतर, यह फ़ंक्शन नॉन-कॉन्स्टेंट संदर्भ ओवरलोड [SWS_CORE_00949] का कॉन्स्टेंट समकक्ष बनाता है। नियमित मान प्रकारों के लिए, Lvalues और Rvalues के लिए समरूप ओवरलोड उपलब्ध हैं ([SWS_CORE_00766], [SWS_CORE_00769], [SWS_CORE_00778]), जबकि ara::core::Result<void, E> के लिए बिना रिटर्न मान वाला एक ओवरलोड परिभाषित है ([SWS_CORE_00866])।

यह उपयोग संबंधी निर्देश R25-11 विनिर्देश के आधार पर स्वचालित रूप से तैयार किया गया था।

टेम्पलेट विशेषज्ञता ara::core::Result<T&, E> का मेंबर फ़ंक्शन ValueOrThrow शामिल संदर्भ मान [SWS_CORE_00949] तक सिंक्रोनस पहुंच के लिए कार्य करता है। यह कोई पैरामीटर स्वीकार नहीं करता है और संग्रहीत मान के लिए एक नॉन-कॉन्स्टेंट संदर्भ T& लौटाता है [SWS_CORE_00949]।

यदि ऑब्जेक्ट में कोई मान नहीं है, बल्कि एक त्रुटि है, तो ऑपरेशन अपवाद-सुरक्षित नहीं (not exception safe) है और त्रुटि से संबंधित प्रकार का एक अपवाद ट्रिगर करता है (noexcept(false)) [SWS_CORE_00949]। इसके उपयोग के लिए एक अनिवार्य सीमा शर्त यह है कि यदि कंपाइलर टूलचेन में C++ अपवाद अक्षम हैं, तो फ़ंक्शन ओवरलोड रिज़ॉल्यूशन में भाग नहीं लेता है [SWS_CORE_00949]।

समवर्तीता के संबंध में, कॉल को थ्रेड-सुरक्षित के रूप में निर्दिष्ट किया गया है [SWS_CORE_00949]। संदर्भों ara::core::Result<T&, E> की विशेषज्ञता के भीतर, एक कॉन्स्टेंट संस्करण के रूप में ओवरलोड [SWS_CORE_00938] मौजूद है, जो const T& प्रदान करता है। यह व्यवहार lvalue संदर्भों [SWS_CORE_00778], const-lvalue संदर्भों [SWS_CORE_00766] और rvalue संदर्भों [SWS_CORE_00769] के लिए प्राथमिक टेम्पलेट ara::core::Result के ओवरलोड्स के साथ-साथ void [SWS_CORE_00866] की विशेषज्ञता को पूरा करता है।
