<pre>The full generated code for AnnotateAttr is:
class AnnotateAttr : public InheritableParamAttr {
unsigned annotationLength;
char *annotation;
public:
static AnnotateAttr *CreateImplicit(ASTContext &Ctx, llvm::StringRef
Annotation, SourceRange Loc = SourceRange()) {
auto *A = new (Ctx) AnnotateAttr(Loc, Ctx, Annotation, 0);
A->setImplicit(true);
return A;
}
AnnotateAttr(SourceRange R, ASTContext &Ctx
, llvm::StringRef Annotation
, unsigned SI
)
: InheritableParamAttr(attr::Annotate, R, SI, false, false)
, annotationLength(Annotation.size()),annotation(new (Ctx, 1)
char[annotationLength])
{
if (!Annotation.empty())
std::memcpy(annotation, Annotation.data(), annotationLength);
}
AnnotateAttr *clone(ASTContext &C) const;
void printPretty(raw_ostream &OS,
const PrintingPolicy &Policy) const;
const char *getSpelling() const;
llvm::StringRef getAnnotation() const {
return llvm::StringRef(annotation, annotationLength);
}
unsigned getAnnotationLength() const {
return annotationLength;
}
void setAnnotation(ASTContext &C, llvm::StringRef S) {
annotationLength = S.size();
this->annotation = new (C, 1) char [annotationLength];
if (!S.empty())
std::memcpy(this->annotation, S.data(), annotationLength);
}
static bool classof(const Attr *A) { return A->getKind() == attr::Annotate; }
};
Destruction of a AnnotateAttr will leak the `annotation` string. So does calls
to `setAnnotation`.</pre>
