Public Functions¶

Type	Name
void	appended (int count) Updates cached statistics after one record was appended, giving count records.
void	collect (const InspectionSource & source, InspectionAxis order, const InspectionBounds & bounds, int offset, int limit, QList< int > & indices)
InspectionHit	nearest (const InspectionSource & source, const InspectionMetric & metric, InspectionAxis order, const QPointF & position, double radius)
InspectionHit	nearestAlong (const InspectionSource & source, const InspectionMetric & metric, InspectionAxis order, double pixel, double radius) const Returns the valid data point nearest to pixel along the ordered axis.
InspectionNeighbors	neighbors (const InspectionSource & source, InspectionAxis order, double value) const Returns the valid data points on either side of value on the ordered axis.
void	reset () Discards cached statistics after the records were replaced or their validity changed.
std::size_t	storageBytes () const Returns the bytes held by cached statistics.
SummaryAccumulator	summarize (const InspectionSource & source, InspectionAxis order, const InspectionBounds & bounds)

Public Static Functions¶

Type	Name
bool	isSorted (const InspectionSource & source, InspectionAxis axis) Returns true when every coordinate of source along__axis is finite and not smaller than its predecessor.

Detailed Description¶

The order argument names the axis whose coordinates are finite and non-decreasing. Positions along it are found by binary search, so no index is built and appended records are visible immediately. Per-block extents and Y statistics are cached lazily to answer large region summaries and to prune nearest-point searches.
