Detailed Description

A little helper class used to produce diagnostics.

This is constructed by the DiagnosticsEngine::Report method, and allows insertion of extra information (arguments and source ranges) into the currently "in flight" diagnostic. When the temporary for the builder is destroyed, the diagnostic is issued.

Note that many of these will be created as temporary objects (many call sites), so we want them to be small and we never want their address taken. This ensures that compilers with somewhat reasonable optimizers will promote the common fields to registers, eliminating increments of the NumArgs field, for example.

Constructor & Destructor Documentation

DiagnosticBuilder()

clang::DiagnosticBuilder::DiagnosticBuilder ( const DiagnosticBuilder &  D )

inline

Copy constructor.

When copied, this "takes" the diagnostic info from the input and neuters it.

Definition at line 1112 of file Diagnostic.h.

References Clear().

~DiagnosticBuilder()

clang::DiagnosticBuilder::~DiagnosticBuilder ( )

inline

Emits the diagnostic.

Definition at line 1123 of file Diagnostic.h.

AddTaggedVal()

void clang::DiagnosticBuilder::AddTaggedVal ( intptr_t  V, DiagnosticsEngine::ArgumentKind  Kind  ) const

inline

Definition at line 1155 of file Diagnostic.h.

Referenced by clang::PartialDiagnostic::Emit(), and clang::operator<<().

Clear()

void clang::DiagnosticBuilder::Clear ( ) const

inlineprotected

Clear out the current diagnostic.

Definition at line 1075 of file Diagnostic.h.

Referenced by DiagnosticBuilder().

Emit()

bool clang::DiagnosticBuilder::Emit ( )

inlineprotected

Force the diagnostic builder to emit the diagnostic now.

Once this function has been called, the DiagnosticBuilder object should not be used again before it is destroyed.

Returns

true if a diagnostic was emitted, false if the diagnostic was suppressed.

Definition at line 1091 of file Diagnostic.h.

FlushCounts()

void clang::DiagnosticBuilder::FlushCounts ( )

inlineprotected

Definition at line 1070 of file Diagnostic.h.

getEmpty()

static DiagnosticBuilder clang::DiagnosticBuilder::getEmpty ( )

inlinestatic

Retrieve an empty diagnostic builder.

Definition at line 1128 of file Diagnostic.h.

isActive()

bool clang::DiagnosticBuilder::isActive ( ) const

inlineprotected

Determine whether this diagnostic is still active.

Definition at line 1082 of file Diagnostic.h.

operator bool()

clang::DiagnosticBuilder::operator bool ( ) const

inline

Conversion of DiagnosticBuilder to bool always returns true.

This allows is to be used in boolean error contexts (where true is used to indicate that an error has occurred), like:

return Diag(...);

Definition at line 1145 of file Diagnostic.h.

operator=()

DiagnosticBuilder& clang::DiagnosticBuilder::operator= ( const DiagnosticBuilder &  )

delete

setForceEmit()

const DiagnosticBuilder& clang::DiagnosticBuilder::setForceEmit ( ) const

inline

Forces the diagnostic to be emitted.

Definition at line 1133 of file Diagnostic.h.
