示例1: update
void NowReadingEngine::update()
{
QFileInfoList okularFiles = getOkularXMLFiles();
QFileInfoList::const_iterator it = okularFiles.constBegin();
uint limit = MaxDataModelSize;
for ( ; it != okularFiles.constEnd() && limit--; ++it) {
QString okularFileName = it->absoluteFilePath();
DataModel::iterator itDm = _dataModel.find(okularFileName);
if ((itDm != _dataModel.end()) && /* We have an entry for this element */
(itDm.value().accessTime >= it->lastModified())) { /* And it's up to date */
/* No need to update */
continue;
}

if (convertOkularXMLFileToEntry(okularFileName, entry)) {
setData(entry.path, "currentPage", entry.currentPage);
setData(entry.path, "totalPages", entry.totalPages);
setData(entry.path, "accessTime", entry.accessTime);
_dataModel[okularFileName] = entry;
}
}
/* Cleanup */
if (_dataModel.size() > MaxDataModelSize) {
// Find elements to evict
// First - what is the modification time of the last element we want to preserve?
QDateTime oldestElementDate;
QList<DataModel::mapped_type> values = _dataModel.values();
nth_element(values.begin(), values.begin()+MaxDataModelSize-1, values.end());

// Now find all elements older than the oldest allowable
DataModel::iterator it = _dataModel.begin();
while (it != _dataModel.end()) {

/* Single shot timer used as in case the update takes very long
we can get overflow of timer events to handle */
