Method Summary

Modifier and Type	Method	Description
static double	build(Path tablePath)	Builds a v1 index at close, using bounded sorted runs rather than retaining geometries.
static double	build(Path tablePath, Runnable cancellation)
static SortedSet<Long>	candidates(Path index, List<Double> grids, ch.so.agi.filegdb.geometry.Envelope filter)	Returns candidate object IDs; consumers must apply their final geometric predicate.
static Path	path(Path table)
static void	validate(Path index, List<Double> grids, Runnable cancellation)
