Geometry.MultiCurve (Geometry v1.2.0)

A multi-curve struct, representing a 2D collection of curves.

A MultiCurve is a collection of curves which can include LineStrings, CircularStrings or CompoundCurves.

Summary

Types

curve()

t()

Functions

new()

Creates an empty MultiCurve.

new(curves, srid \\ 0)

Creates a MultiCurve from the given curves.

Types

curve()

@type curve() ::
  Geometry.LineString.t()
  | Geometry.CircularString.t()
  | Geometry.CompoundCurve.t()

t()

@type t() :: %Geometry.MultiCurve{curves: [curve()], srid: Geometry.srid()}

Functions

new()

@spec new() :: t()

Creates an empty MultiCurve.

Examples

iex> Geometry.MultiCurve.new()
%Geometry.MultiCurve{curves: [], srid: 0}

new(curves, srid \\ 0)

@spec new([curve()], Geometry.srid()) :: t()

Creates a MultiCurve from the given curves.

Examples

iex> Geometry.MultiCurve.new([
...>   Geometry.LineString.new([
...>     Geometry.Point.new(0, 0),
...>     Geometry.Point.new(5, 5)
...>   ]),
...>   Geometry.CircularString.new([
...>     Geometry.Point.new(4, 0),
...>     Geometry.Point.new(4, 4),
...>     Geometry.Point.new(8, 4)
...>   ])
...> ])
%Geometry.MultiCurve{
  curves: [
    %Geometry.LineString{path: [[0, 0], [5, 5]], srid: 0},
    %Geometry.CircularString{arcs: [[4, 0], [4, 4], [8, 4]], srid: 0}
  ],
  srid: 0
