示例1: DoSearch
void Engine::DoSearch(SearchParams const & params, m2::RectD const & viewport,
shared_ptr<ProcessorHandle> handle, Processor & processor)
{
bool const viewportSearch = params.m_mode == Mode::Viewport;
processor.Reset();
processor.Init(viewportSearch);
handle->Attach(processor);
MY_SCOPE_GUARD(detach, [&handle]
{
handle->Detach();
});
// Early exit when query processing is cancelled.
if (processor.IsCancelled())
{
Results results;
results.SetEndMarker(true /* isCancelled */);
params.m_onResults(results);
