Class Curve

The base type for all 1-dimensional geometry types. A 1-dimensional geometry is a geometry that has a length, but no area. A curve is considered simple if it does not intersect itself (except at the start and end point). A curve is considered closed its start and end point are coincident. A simple, closed curve is called a ring.

Accessors

geometryType

hasM

  • get hasM(): boolean
  • set hasM(hasM: boolean): void
  • Does the geometry have m coordinates

    Returns boolean

    true if has m coordinates

  • Set if the geometry has m coordinates

    Parameters

    • hasM: boolean

      true if has m coordinates

    Returns void

    true if has m coordinates

hasZ

  • get hasZ(): boolean
  • set hasZ(hasZ: boolean): void
  • Does the geometry have z coordinates

    Returns boolean

    true if has z coordinates

  • Set if the geometry has z coordinates

    Parameters

    • hasZ: boolean

      true if has z coordinates

    Returns void

    true if has z coordinates

is3D

  • get is3D(): boolean
  • Does the geometry have z coordinates

    see

    #hasZ()

    Returns boolean

    true if has z coordinates

Methods

Abstract copy

Abstract endPoint

Abstract equals

expandEnvelope

getCentroid

  • Get the mathematical centroid point of a 2 dimensional representation of the Geometry (balancing point of a 2d cutout of the geometry). Only the x and y coordinate of the resulting point are calculated and populated. The resulting {@link Point#getZ()} and {@link Point#getM()} methods will always return null.

    Returns Point

    centroid point

getDegreesCentroid

  • getDegreesCentroid(): Point
  • Get the geographic centroid point of a 2 dimensional representation of the degree unit Geometry. Only the x and y coordinate of the resulting point are calculated and populated. The resulting {@link Point#getZ()} and {@link Point#getM()} methods will always return null.

    Returns Point

    centroid point

getDimension

  • getDimension(): number

getEnvelope

isClosed

  • isClosed(): boolean
  • Determine if this Curve is closed (start point = end point)

    Returns boolean

    true if closed

Abstract isEmpty

  • isEmpty(): boolean

isMeasured

  • isMeasured(): boolean

Abstract isSimple

  • isSimple(): boolean
  • Determine if this Geometry has no anomalous geometric points, such as self intersection or self tangency

    Returns boolean

    true if simple

Abstract startPoint

updateZM

Static hasM

  • hasM(geometries: Array<Geometry>): boolean
  • Determine if the geometries contain a M value

    Parameters

    • geometries: Array<Geometry>

      list of geometries

    Returns boolean

    true if has m

Static hasZ

  • hasZ(geometries: Array<Geometry>): boolean
  • Determine if the geometries contain a Z value

    Parameters

    • geometries: Array<Geometry>

      list of geometries

    Returns boolean

    true if has z
