Geometry.GeometryCollectionM (Geometry v1.1.0)

A collection set of 2D geometries with a measurement.

GeometryCollectionM implements the protocols Enumerable and Collectable.

Examples

iex> Enum.map(
...>   GeometryCollectionM.new([
...>     PointM.new(11, 12, 14),
...>     LineStringM.new([
...>       PointM.new(21, 22, 24),
...>       PointM.new(31, 32, 34)
...>     ])
...>   ]),
...>   fn
...>     %PointM{} -> :point
...>     %LineStringM{} -> :line_string
...>   end
...> ) |> Enum.sort()
[:line_string, :point]

iex> Enum.into([PointM.new(1, 2, 4)], GeometryCollectionM.new())
%GeometryCollectionM{geometries: [%PointM{coordinates: [1, 2, 4]}], srid: 0}
