Geometry.MultiLineStringZM (Geometry v1.1.0)

A set of line-strings from type Geometry.LineStringZM

MultiLineStringZM implements the protocols Enumerable and Collectable.

Examples

iex> Enum.map(
...>   MultiLineStringZM.new([
...>     LineStringZM.new([
...>       PointZM.new(1, 2, 3, 4),
...>       PointZM.new(3, 4, 5, 6)
...>     ]),
...>     LineStringZM.new([
...>       PointZM.new(1, 2, 3, 4),
...>       PointZM.new(11, 12, 13, 14),
...>       PointZM.new(13, 14, 15, 16)
...>     ])
...>   ]),
...>   fn line_string -> length line_string end
...> )
[2, 3]

iex> Enum.into(
...>   [LineStringZM.new([PointZM.new(1, 2, 3, 4), PointZM.new(5, 6, 7, 8)])],
...>   MultiLineStringZM.new())
%MultiLineStringZM{line_strings: [[[1, 2, 3, 4], [5, 6, 7, 8]]]}
