MvtLineString

class MvtLineString(val coordinates: Array<MvtCoordinate>) : MvtGeometry

An open or closed run of coordinates.

MVT polygon rings use this same type. JTS modelled rings as a LinearRing subclass, but nothing in this codebase distinguished the two -- rings and lines are both consumed through coordinates. Ring closure is preserved exactly as decoded: the ClosePath command appends a duplicate of the first vertex, and the renderers strip that trailing duplicate themselves.

Constructors

Properties

val coordinates: Array<MvtCoordinate>

envelopeInternal

open override val envelopeInternal: MvtEnvelope

Cached like JTS cached its own; hit-testing calls this per feature on every tap.

open override val isEmpty: Boolean

True when this geometry carries no coordinates.

open val numGeometries: Int

1 for a single geometry, the child count for a multi-geometry, 0 for the empty one.

val numPoints: Int

Functions

open fun getGeometryN(n: Int): MvtGeometry

Mirrors Geometry.getGeometryN: returns this for single geometries.
