示例1: getParentASTContext

/// \brief Load the declarations within this lexical storage from an
/// external source.
void
DeclContext::LoadLexicalDeclsFromExternalStorage() const {
  ExternalASTSource *Source = getParentASTContext().getExternalSource();
  assert(hasExternalLexicalStorage() && Source && "No external storage?");

  llvm::SmallVector<uint32_t, 64> Decls;
  if (Source->ReadDeclsLexicallyInContext(const_cast<DeclContext *>(this),
                                          Decls))
    return;

  // There is no longer any lexical storage in this context
  ExternalLexicalStorage = false;

  if (Decls.empty())
    return;

  // Resolve all of the declaration IDs into declarations, building up
  // a chain of declarations via the Decl::NextDeclInContext field.
  Decl *FirstNewDecl = 0;
  Decl *PrevDecl = 0;
  for (unsigned I = 0, N = Decls.size(); I != N; ++I) {
    Decl *D = Source->GetDecl(Decls[I]);
    if (PrevDecl)
      PrevDecl->NextDeclInContext = D;
    else
      FirstNewDecl = D;

    PrevDecl = D;
  }

  // Splice the newly-read declarations into the beginning of the list
  // of declarations.
  PrevDecl->NextDeclInContext = FirstDecl;
  FirstDecl = FirstNewDecl;
  if (!LastDecl)
    LastDecl = PrevDecl;
