Member Function Documentation

virtual void clang::DiagnosticConsumer::BeginSourceFile ( const LangOptions LangOpts,
const Preprocessor PP = nullptr 
) [inline, virtual]

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

Reimplemented in clang::VerifyDiagnosticConsumer, clang::LogDiagnosticPrinter, clang::TextDiagnosticPrinter, and clang::ChainedDiagnosticConsumer.

virtual void clang::DiagnosticConsumer::clear ( ) [inline, virtual]

void DiagnosticConsumer::HandleDiagnostic ( DiagnosticsEngine::Level  DiagLevel,
const Diagnostic Info 
) [virtual]

Indicates whether the diagnostics handled by this DiagnosticConsumer should be included in the number of diagnostics reported by DiagnosticsEngine.

The default implementation returns true.

IncludeInDiagnosticCounts - This method (whose default implementation returns true) indicates whether the diagnostics handled by this DiagnosticConsumer should be included in the number of diagnostics reported by DiagnosticsEngine.
