Methods

virtual clang::TypoCorrection CorrectTypo(
    const clang::DeclarationNameInfo& Typo,
    int LookupKind,
    clang::Scope* S,
    clang::CXXScopeSpec* SS,
    clang::CorrectionCandidateCallback& CCC,
    clang::DeclContext* MemberContext,
    bool EnteringContext,
    const clang::ObjCObjectPointerType* OPT)

Description

\copydoc Sema::CorrectTypo ExternalSemaSource::CorrectTypo is always given the first chance to correct a typo (really, to offer suggestions to repair a failed lookup). It will even be called when SpellChecking is turned off or after a fatal error has already been detected.

Declared at: clang/include/clang/Sema/ExternalSemaSource.h:210

Parameters

const clang::DeclarationNameInfo& Typo
int LookupKind
clang::Scope* S
clang::CXXScopeSpec* SS
clang::CorrectionCandidateCallback& CCC
clang::DeclContext* MemberContext
bool EnteringContext
const clang::ObjCObjectPointerType* OPT

virtual void ForgetSema()

Description

Inform the semantic consumer that Sema is no longer available.

Declared at: clang/include/clang/Sema/ExternalSemaSource.h:65

virtual void InitializeSema(clang::Sema& S)

Description

Initialize the semantic source with the Sema instance being used to perform semantic analysis on the abstract syntax tree.

Declared at: clang/include/clang/Sema/ExternalSemaSource.h:62

Parameters

clang::Sema& S

virtual bool LookupUnqualified(
    clang::LookupResult& R,
    clang::Scope* S)

Description

Do last resort, unqualified lookup on a LookupResult that Sema cannot find.

Declared at: clang/include/clang/Sema/ExternalSemaSource.h:96

Parameters

clang::LookupResult& R
a LookupResult that is being recovered.
clang::Scope* S
the Scope of the identifier occurrence.

Returns

true to tell Sema to recover using the LookupResult.

virtual bool MaybeDiagnoseMissingCompleteType(
    clang::SourceLocation Loc,
    clang::QualType T)

Description

Produces a diagnostic note if the external source contains a complete definition for \p T.

Declared at: clang/include/clang/Sema/ExternalSemaSource.h:228

Parameters

clang::SourceLocation Loc
the location at which a complete type was required but not provided
clang::QualType T
