Geometry.CircularStringM
(Geometry v1.2.0)
View Source
A circular-string struct, representing a 2D curve with a measurement.
A non-empty circular-string requires at least three coordinates. In a sequence of arcs the end point of the previous arc is the start point of the next arc, just like the segments of a LineString. This means that a CircularString must have an odd number of points greater than 1.
Summary
Functions
Creates an empty CircularStringM.
Creates a CircularStringM from the given Geometry.PointMs.
Types
@type t() :: %Geometry.CircularStringM{arcs: Geometry.arcs(), srid: Geometry.srid()}
Functions
@spec new() :: t()
Creates an empty CircularStringM.
Examples
iex> CircularStringM.new()
%CircularStringM{arcs: [], srid: 0}@spec new([Geometry.PointM.t()], Geometry.srid()) :: t()
Creates a CircularStringM from the given Geometry.PointMs.
Examples
iex> CircularStringM.new(
...> [PointM.new(1, 2, 3), PointM.new(3, 4, 5), PointM.new(5, 6, 7)])
%CircularStringM{arcs: [[1, 2, 3], [3, 4, 5], [5, 6, 7]], srid: 0}
