Geometry.MultiCurveZM (Geometry v1.2.0)

A multi-curve struct, representing a 4D 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 MultiCurveZM.

new(curves, srid \\ 0)

Creates a MultiCurveZM from the given curves.

Types

curve()

@type curve() ::
  Geometry.LineStringZM.t()
  | Geometry.CircularStringZM.t()
  | Geometry.CompoundCurveZM.t()

t()

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

Functions

new()

@spec new() :: t()

Creates an empty MultiCurveZM.

Examples

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

new(curves, srid \\ 0)

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

Creates a MultiCurveZM from the given curves.

Examples

iex> Geometry.MultiCurveZM.new([
...>   Geometry.LineStringZM.new([
...>     Geometry.PointZM.new(0, 0, 1, 5),
...>     Geometry.PointZM.new(5, 5, 2, 5)
