Public Member Functions
VerifyDiagnosticConsumer (DiagnosticsEngine &Diags)
Create a new verifying diagnostic client, which will issue errors to the currently-attached diagnostic client when a diagnostic does not match what is expected (as indicated in the source file).
~VerifyDiagnosticConsumer () override
void BeginSourceFile (const LangOptions &LangOpts, const Preprocessor *PP) override
Callback to inform the diagnostic client that processing of a source file is beginning.
void EndSourceFile () override
Callback to inform the diagnostic client that processing of a source file has ended.
void UpdateParsedFileStatus (SourceManager &SM, FileID FID, ParsedStatus PS)
Update lists of parsed and unparsed files.
bool HandleComment (Preprocessor &PP, SourceRange Comment) override
HandleComment - Hook into the preprocessor and extract comments containing expected errors and warnings.
void HandleDiagnostic (DiagnosticsEngine::Level DiagLevel, const Diagnostic &Info) override
Handle this diagnostic, reporting it to the user or capturing it to a log as needed.

◆ HandleComment()

◆ HandleDiagnostic()

Handle this diagnostic, reporting it to the user or capturing it to a log as needed.

The default implementation just keeps track of the total number of warnings and errors.

Reimplemented from clang::DiagnosticConsumer.
