Revision.

getType(){ol.geom.GeometryType}

src/ol/geom/point.js, line 86

Get the type of this geometry.

Returns:

Geometry type.

intersectsCoordinate(coordinate){boolean} inherited

src/ol/geom/geometry.js, line 112

Returns true if this geometry includes the specified coordinate. If the coordinate is on the boundary of the geometry, returns false.

Name	Type	Description
