Methods

appendLineString

  • appendLineString(lineString): void

  • Append the passed linestring to the multilinestring.

    Parameters

    Returns void

    Api

    stable

applyTransform

changed

  • changed(): void

  • Increases the revision counter and dispatches a 'change' event.

    Returns void

    Api

clone

dispatchEvent

  • dispatchEvent(event): void

  • Dispatches an event and calls all listeners listening for events of this type. The event parameter can either be a string or an Object with a type property.

    Parameters

    Returns void

    Function

    Api

get

  • get(key): any

  • Gets a value.

    Parameters

    • key: string

      Key name.

    Returns any

    Value.

getClosestPoint

getCoordinateAtM

  • getCoordinateAtM(m, opt_extrapolate?, opt_interpolate?): Coordinate

  • Returns the coordinate at m using linear interpolation, or null if no such coordinate exists.

    opt_extrapolate controls extrapolation beyond the range of Ms in the MultiLineString. If opt_extrapolate is true then Ms less than the first M will return the first coordinate and Ms greater than the last M will return the last coordinate.

    opt_interpolate controls interpolation between consecutive LineStrings within the MultiLineString. If opt_interpolate is true the coordinates will be linearly interpolated between the last coordinate of one LineString and the first coordinate of the next LineString. If opt_interpolate is false then the function will return null for Ms falling between LineStrings.

    Parameters

    • m: number

      M.

    • Optional opt_extrapolate: boolean

      Extrapolate. Default is false.

    • Optional opt_interpolate: boolean

simplify

  • simplify(tolerance): ov2D3D.MapClient.ol.geom.Geometry

  • Create a simplified version of this geometry. For linestrings, this uses the the Douglas Peucker algorithm. For polygons, a quantization-based simplification is used to preserve topology.

    Parameters

    • tolerance: number

      The tolerance distance for simplification.

    Returns ov2D3D.MapClient.ol.geom.Geometry

    A new, simplified version of the original geometry.

transform

  • transform(source, destination): ov2D3D.MapClient.ol.geom.Geometry

  • Transform each coordinate of the geometry from one coordinate reference system to another. The geometry is modified in place. For example, a line will be transformed to a line and a circle to a circle. If you do not want the geometry modified in place, first clone() it and then use this function on the clone.

    Parameters

    Returns ov2D3D.MapClient.ol.geom.Geometry

    This geometry. Note that original geometry is modified in place.
