◆ CorrectTypo()

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

overridevirtual

Try to "correct" a typo in the source code by finding visible declarations whose names are similar to the name that was present in the source code.

Parameters

TypoName	the `DeclarationNameInfo` structure that contains the name that was present in the source code along with its location.
LookupKind	the name-lookup criteria used to search for the name.
S	the scope in which name lookup occurs.
SS	the nested-name-specifier that precedes the name we're looking for, if present.
CCC	A CorrectionCandidateCallback object that provides further validation of typo correction candidates. It also provides flags for determining the set of keywords permitted.
MemberContext	if non-NULL, the context in which to look for a member access expression.
EnteringContext	whether we're entering the context described by the nested-name-specifier SS.
OPT	when non-NULL, the search for visible declarations will also walk the protocols in the qualified interfaces of `OPT`.

Returns: a TypoCorrection containing the corrected name if the typo along with information such as the NamedDecl where the corrected name was declared, and any additional NestedNameSpecifier needed to access it (C++ only). The TypoCorrection is empty if there is no correction.

Note: LookupKind must correspond to a valid Sema::LookupNameKind

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.

Note: Returns the first nonempty correction.

		llvm::DenseMap< const CXXRecordDecl *, CharUnits > &	BaseOffsets,
		llvm::DenseMap< const CXXRecordDecl *, CharUnits > &	VirtualBaseOffsets
	)

overridevirtual

Perform layout on the given record.

This routine allows the external AST source to provide an specific layout for a record, overriding the layout that would normally be constructed. It is intended for clients who receive specific layout details rather than source code (such as LLDB). The client is expected to fill in the field offsets, base offsets, virtual base offsets, and complete object size.

Parameters

Record	The record whose layout is being requested.
Size	The final size of the record, in bits.
Alignment	The final alignment of the record, in bits.
FieldOffsets	The offset of each of the fields within the record, expressed in bits. All of the fields must be provided with offsets.
BaseOffsets	The offset of each of the direct, non-virtual base classes. If any bases are not given offsets, the bases will be laid out according to the ABI.
VirtualBaseOffsets	The offset of each of the virtual base classes (either direct or not). If any bases are not given offsets, the bases will be laid out according to the ABI.

Returns: true if the record layout was provided, false otherwise.
