示例1: Serialize

void
nsTreeContentView::SerializeItem(Element* aContent, int32_t aParentIndex,
                                 int32_t* aIndex, nsTArray<UniquePtr<Row>>& aRows)
{
  if (aContent->AttrValueIs(kNameSpaceID_None, nsGkAtoms::hidden,
                            nsGkAtoms::_true, eCaseMatters))
    return;

  aRows.AppendElement(MakeUnique<Row>(aContent, aParentIndex));
  Row* row = aRows.LastElement().get();

  if (aContent->AttrValueIs(kNameSpaceID_None, nsGkAtoms::container,
                            nsGkAtoms::_true, eCaseMatters)) {
    row->SetContainer(true);
    if (aContent->AttrValueIs(kNameSpaceID_None, nsGkAtoms::open,
                              nsGkAtoms::_true, eCaseMatters)) {
      row->SetOpen(true);
      nsIContent* child =
        nsTreeUtils::GetImmediateChild(aContent, nsGkAtoms::treechildren);
      if (child && child->IsXULElement()) {
        // Now, recursively serialize our child.
        int32_t count = aRows.Length();
        int32_t index = 0;
        Serialize(child, aParentIndex + *aIndex + 1, &index, aRows);
        row->mSubtreeSize += aRows.Length() - count;
      }
      else
        row->SetEmpty(true);
    } else if (aContent->AttrValueIs(kNameSpaceID_None, nsGkAtoms::empty,
                                     nsGkAtoms::_true, eCaseMatters)) {
