public final class VectorFeature

Object
VectorFeature

A single decoded feature of a Mapbox Vector Tile: its geometry type, its attribute map, and its geometry as one or more parts in tile-local coordinates (0..VectorLayer.getExtent, origin top-left).

For GEOM_POINT each part is a flat run of x,y points; for GEOM_LINESTRING each part is a polyline; for GEOM_POLYGON each part is a closed ring (exterior rings wind one way, holes the other, per the MVT spec).

Fields

`public static final int GEOM_UNKNOWN = 0`	Unknown / empty geometry.
`public static final int GEOM_POINT = 1`	One or more points.
`public static final int GEOM_LINESTRING = 2`	One or more polylines.
`public static final int GEOM_POLYGON = 3`	One or more polygon rings.

Methods

`public long getId()`	The feature id (0 when absent).
`public int getGeometryType()`	One of the `GEOM_*` constants.
`public` `Map getAttributes()`	The feature attributes as a `Map<String,Object>` (string/number/bool).
`public` `Object getAttribute(String key)`	Convenience accessor for a single attribute, or `null`.
`public` `List getParts()`	The geometry parts, each an `int[]` of interleaved `x,y` tile-local coordinates.
