示例1: getPointAnnotationsInBounds
AnnotationIDs AnnotationManager::getPointAnnotationsInBounds(const LatLngBounds& bounds) const {
AnnotationIDs result;
pointTree.query(boost::geometry::index::intersects(bounds),
boost::make_function_output_iterator([&](const auto& val){
result.push_back(val->id);
}));
return result;
}示例2: make_pair
std::pair<std::unordered_set<TileID, TileID::Hash>, AnnotationIDs>
AnnotationManager::addPointAnnotations(const std::vector<PointAnnotation>& points,
const uint8_t maxZoom) {
// We pre-generate tiles to contain each annotation up to the map's max zoom.
// We do this for fast rendering without projection conversions on the fly, as well as
// to simplify bounding box queries of annotations later. Tiles get invalidated when
// annotations are added or removed in order to refresh the map render without
// touching the base map underneath.
AnnotationIDs annotationIDs;
annotationIDs.reserve(points.size());
std::unordered_set<TileID, TileID::Hash> affectedTiles;
for (const PointAnnotation& point : points) {

// at render time we style the point according to its {sprite} field

// Tile:IDs that need refreshed and the annotation identifiers held onto by the client.

}示例3:
AnnotationIDs
