◆ CorrectTypo()

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](classclang%5F1%5F1TypoCorrection.html "Simple class containing the result of Sema::CorrectTypo.") containing the corrected name if the typo along with information such as the [NamedDecl](classclang%5F1%5F1NamedDecl.html "This represents a decl that may have a name.") where the corrected name was declared, and any additional [NestedNameSpecifier](classclang%5F1%5F1NestedNameSpecifier.html "Represents a C++ nested name specifier, such as "\::std::vector<int>::".") needed to access it (C++ only). The [TypoCorrection](classclang%5F1%5F1TypoCorrection.html "Simple class containing the result of Sema::CorrectTypo.") is empty if there is no correction.

Note

LookupKind must correspond to a valid Sema::LookupNameKind

[ExternalSemaSource::CorrectTypo](classclang%5F1%5F1ExternalSemaSource.html#a3febc2b905546ca1fc38ada315b6a0ed "Try to "correct" a typo in the source code by finding visible declarations whose names are similar to...") 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.

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.
