C++ (Cpp) LoadPageLinks Examples

Example #1

File: cpdf_linklist.cpp Project: gradescope/pdfium

const std::vector<CPDF_Dictionary*>* CPDF_LinkList::GetPageLinks(
    CPDF_Page* pPage) {
  uint32_t objnum = pPage->m_pFormDict->GetObjNum();
  if (objnum == 0)
    return nullptr;

  auto it = m_PageMap.find(objnum);
  if (it != m_PageMap.end())
    return &it->second;

  // std::map::operator[] forces the creation of a map entry.
  std::vector<CPDF_Dictionary*>& page_link_list = m_PageMap[objnum];
  LoadPageLinks(pPage, &page_link_list);
  return &page_link_list;
}
