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.

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::~VerifyDiagnosticConsumer ( )	override

◆ BeginSourceFile()

Callback to inform the diagnostic client that processing of a source file is beginning.

Note that diagnostics may be emitted outside the processing of a source file, for example during the parsing of command line options. However, diagnostics with source range information are required to only be emitted in between BeginSourceFile() and EndSourceFile().

Parameters

LangOpts	The language options for the source file being processed.
PP	The preprocessor object being used for the source; this is optional, e.g., it may not be present when processing AST source files.
