示例1: materializeDecls

void StoredDeclsList::materializeDecls(ASTContext &Context) {
  if (isNull())
    return;

  switch ((DataKind)(Data & 0x03)) {
  case DK_Decl:
  case DK_Decl_Vector:
    break;

  case DK_DeclID: {
    // Resolve this declaration ID to an actual declaration by
    // querying the external AST source.
    unsigned DeclID = Data >> 2;

    ExternalASTSource *Source = Context.getExternalSource();
    assert(Source && "No external AST source available!");

    Data = reinterpret_cast<uintptr_t>(Source->GetExternalDecl(DeclID));
    break;
  }

  case DK_ID_Vector: {
    // We have a vector of declaration IDs. Resolve all of them to
    // actual declarations.
    VectorTy &Vector = *getAsVector();
    ExternalASTSource *Source = Context.getExternalSource();
    assert(Source && "No external AST source available!");

    for (unsigned I = 0, N = Vector.size(); I != N; ++I)
      Vector[I] = reinterpret_cast<uintptr_t>(Source->GetExternalDecl(Vector[I]));

    Data = (Data & ~0x03) | DK_Decl_Vector;
    break;
  }
  }
}
