		FileManager &	FromFileManager,
		bool	MinimalImport,
		std::shared_ptr< ASTImporterSharedState >	SharedState = nullptr )

FromContext	The context we'll be importing from.
FromFileManager	The file manager we'll be importing into.
MinimalImport	If true, the importer will attempt to import as little as it can, e.g., by importing declarations as forward declarations that can be completed at a later point.
SharedState	The importer specific lookup table which may be shared amongst several ASTImporter objects. If not set then the original C/C++ lookup is used.

CompleteDecl()

void ASTImporter::CompleteDecl ( Decl * D )

virtual

Called for ObjCInterfaceDecl, ObjCProtocolDecl, and TagDecl.

Mark the Decl as complete, filling it in as much as possible.

Parameters

D	A declaration in the "to" context.

FromDiag()

DiagnosticBuilder ASTImporter::FromDiag	(	SourceLocation	Loc,

GetAlreadyImportedOrNull()

Decl * ASTImporter::GetAlreadyImportedOrNull

(

const Decl *

FromD

)

const

Return the copy of the given declaration in the "to" context if it has already been imported from the "from" context.

Otherwise return nullptr.

Definition at line 9712 of file ASTImporter.cpp.

Referenced by Import().

getFieldIndex()

UnsignedOrNone ASTImporter::getFieldIndex ( Decl * F )

static

Determine the index of a field in its parent record.

F should be a field (or indirect field) declaration.

Returns

The index of the field in its parent context (starting from 0). On error std::nullopt is returned (parent context is non-record).

getFromContext()

ASTContext & clang::ASTImporter::getFromContext ( ) const

inline

Retrieve the context that AST nodes are being imported from.

Definition at line 536 of file ASTImporter.h.

getFromFileManager()

FileManager & clang::ASTImporter::getFromFileManager ( ) const

inline

Retrieve the file manager that AST nodes are being imported from.

Definition at line 542 of file ASTImporter.h.

GetFromTU()

TranslationUnitDecl * ASTImporter::GetFromTU

(

Decl *

ToD

)

Return the translation unit from where the declaration was imported.

If it does not exist nullptr is returned.

References clang::Decl::getTranslationUnitDecl().

getImportDeclErrorIfAny()

std::optional< ASTImportError > ASTImporter::getImportDeclErrorIfAny

(

Decl *

FromD

)

const

Return if import of the given declaration has failed and if yes the kind of the problem.

This gives the first error encountered with the node.

getImportedFromDecl()

template<typename DeclT>

std::optional< DeclT * > clang::ASTImporter::getImportedFromDecl ( const DeclT * ToD ) const

inline

Return the declaration in the "from" context from which the declaration in the "to" context was imported.

If it was not imported or of the wrong type a null value is returned.

Definition at line 371 of file ASTImporter.h.

getNonEquivalentDecls()

Definition at line 551 of file ASTImporter.h.

GetOriginalDecl()

virtual Decl * clang::ASTImporter::GetOriginalDecl ( Decl * To )

inlinevirtual

Called by StructuralEquivalenceContext.

If a RecordDecl is being compared to another RecordDecl as part of import, completing the other RecordDecl may trigger importation of the first RecordDecl. This happens especially for anonymous structs. If the original of the second RecordDecl can be found, we can complete it without the need for importation, eliminating this loop.

Definition at line 576 of file ASTImporter.h.

getToContext()

ASTContext & clang::ASTImporter::getToContext ( ) const

inline

Retrieve the context that AST nodes are being imported into.

getToFileManager()

FileManager & clang::ASTImporter::getToFileManager ( ) const

inline

HandleNameConflict()

Expected< DeclarationName > ASTImporter::HandleNameConflict ( DeclarationName Name, DeclContext * DC, unsigned IDNS, NamedDecl ** Decls, unsigned NumDecls )

virtual

Cope with a name conflict when importing a declaration into the given context.

This routine is invoked whenever there is a name conflict while importing a declaration. The returned name will become the name of the imported declaration. By default, the returned name is the same as the original name, leaving the conflict unresolve such that name lookup for this name is likely to find an ambiguity later.

Subclasses may override this routine to resolve the conflict, e.g., by renaming the declaration being imported.

Parameters

Name	the name of the declaration being imported, which conflicts with other declarations.
DC	the declaration context (in the "to" AST context) in which the name is being imported.
IDNS	the identifier namespace in which the name will be found.
Decls	the set of declarations with the same name as the declaration being imported.
NumDecls	the number of conflicting declarations in Decls.

Returns

the name that the newly-imported declaration should have. Or an error if we can't handle the name conflict.

Imported()

virtual void clang::ASTImporter::Imported ( Decl * From, Decl * To )

inlinevirtual

Subclasses can override this function to observe all of the From -> To declaration mappings as they are imported.

ImportImpl()

Expected< Decl * > ASTImporter::ImportImpl ( Decl * From )

protectedvirtual

Can be overwritten by subclasses to implement their own import logic.

The overwritten method should call this method if it didn't import the decl on its own.

Parameters

To	Import the object into this variable.
From	Object to import.

Returns

MapImported()

Decl * ASTImporter::MapImported	(	Decl *	From,
