z
open override fun zOrderFor(layerName: String, geometryType: MvtGeometryType, properties: Map<String, Any?>): Int
Optional paint order within a tile. Features with smaller zOrderFor paint first, features with larger values paint over them. Default 0 — every feature shares the same z-layer, and the order falls through to MVT-server-determined layer iteration order (good enough for OpenMapTiles-schema servers that already order water → landuse → roads → buildings sensibly).
Standard convention: MvtStyle.Z_* constants — see the companion. Override per-style when the default order conflicts with the visual intent.
