C++ (Cpp) KstRVectorPtr::isValid Examples

Example #1

bool KstIfaceImpl::changeDataFile(const QString& vector, const QString& fileName, bool update) {
  KST::vectorList.lock().readLock();
  KstRVectorPtr rvp = kst_cast<KstRVector>(*KST::vectorList.findTag(vector));
  KST::vectorList.lock().unlock();
  if (!rvp) {
    return false;
  }

  KST::dataSourceList.lock().writeLock();
  KstDataSourceList::Iterator it = KST::dataSourceList.findReusableFileName(fileName);
  KstDataSourcePtr file;
  QString invalidSources;

  if (it == KST::dataSourceList.end()) {
    file = KstDataSource::loadSource(fileName);
    if (!file || !file->isValid() || file->isEmpty()) {
      KST::dataSourceList.lock().unlock();
      return false;
    }
    KST::dataSourceList.append(file);
  } else {
    file = *it;
  }

  KST::dataSourceList.lock().unlock();

  rvp->writeLock();
  file->writeLock();

  if (!file->isValidField(vector)) {
    file->unlock();
    rvp->unlock();
    return false;
  }

  rvp->changeFile(file);
  
  file->unlock();
  bool rc = rvp->isValid();
  rvp->unlock();

  if (update) {
    KstApp::inst()->forceUpdate();
  }

  return rc;
}

Example #2

KJS::Value KstBindDataVector::valid(KJS::ExecState *exec) const {
  Q_UNUSED(exec)
  KstRVectorPtr v = makeDataVector(_d);
  KstReadLocker rl(v);
  return KJS::Boolean(v->isValid());
