示例1: CollectVisibleConversions

/// Collect the visible conversions of a class.
///
/// This would be extremely straightforward if it weren't for virtual
/// bases.  It might be worth special-casing that, really.
static void CollectVisibleConversions(ASTContext &Context,
                                      CXXRecordDecl *Record,
                                      UnresolvedSetImpl &Output) {
  // The collection of all conversions in virtual bases that we've
  // found.  These will be added to the output as long as they don't
  // appear in the hidden-conversions set.
  UnresolvedSet<8> VBaseCs;
  
  // The set of conversions in virtual bases that we've determined to
  // be hidden.
  llvm::SmallPtrSet<NamedDecl*, 8> HiddenVBaseCs;

  // The set of types hidden by classes derived from this one.
  llvm::SmallPtrSet<CanQualType, 8> HiddenTypes;

  // Go ahead and collect the direct conversions and add them to the
  // hidden-types set.
  UnresolvedSetImpl &Cs = *Record->getConversionFunctions();
  Output.append(Cs.begin(), Cs.end());
  for (UnresolvedSetIterator I = Cs.begin(), E = Cs.end(); I != E; ++I)
    HiddenTypes.insert(GetConversionType(Context, I.getDecl()));

  // Recursively collect conversions from base classes.
  for (CXXRecordDecl::base_class_iterator
         I = Record->bases_begin(), E = Record->bases_end(); I != E; ++I) {
    const RecordType *RT = I->getType()->getAs<RecordType>();
    if (!RT) continue;

    CollectVisibleConversions(Context, cast<CXXRecordDecl>(RT->getDecl()),
                              I->isVirtual(), I->getAccessSpecifier(),
                              HiddenTypes, Output, VBaseCs, HiddenVBaseCs);
  }

  // Add any unhidden conversions provided by virtual bases.
  for (UnresolvedSetIterator I = VBaseCs.begin(), E = VBaseCs.end();
         I != E; ++I) {
    if (!HiddenVBaseCs.count(cast<NamedDecl>(I.getDecl()->getCanonicalDecl())))
      Output.addDecl(I.getDecl(), I.getAccess());
  }
