Class MultiLineString

java.lang.Object

com.mapbox.geojson.MultiLineString

All Implemented Interfaces:

CoordinateContainer<java.util.List<java.util.List<Point>>>, GeoJson, Geometry, java.io.Serializable

public final class MultiLineString
extends java.lang.Object
implements CoordinateContainer<java.util.List<java.util.List<Point>>>

A multilinestring is an array of LineString coordinate arrays.

This adheres to the RFC 7946 internet standard when serialized into JSON. When deserialized, this class becomes an immutable object which should be initiated using its static factory methods.

When representing a LineString that crosses the antimeridian, interoperability is improved by modifying their geometry. Any geometry that crosses the antimeridian SHOULD be represented by cutting it in two such that neither part's representation crosses the antimeridian.

For example, a line extending from 45 degrees N, 170 degrees E across the antimeridian to 45 degrees N, 170 degrees W should be cut in two and represented as a MultiLineString.

A sample GeoJson MultiLineString's provided below (in it's serialized state).

 {
   "type": "MultiLineString",
   "coordinates": [
     [
       [100.0, 0.0],
       [101.0, 1.0]
     ],
     [
       [102.0, 2.0],
       [103.0, 3.0]
     ]
   ]
 }
 

Look over the LineString documentation to get more information about formatting your list of linestring objects correctly.

                                       java.lang.String json)

Create a new instance of this class by passing in a formatted valid JSON String. If you are creating a MultiLineString object from scratch it is better to use one of the other provided static factory methods such as fromLineStrings(List).

Parameters:

json - a formatted valid JSON string defining a GeoJson MultiLineString

Returns:

a new instance of this class defined by the values passed inside this static factory method

Since:

1.0.0

fromLineStrings

public static MultiLineString fromLineStrings(@NonNull
                                              java.util.List<LineString> lineStrings)

Create a new instance of this class by defining a list of LineString objects and passing that list in as a parameter in this method. The LineStrings should comply with the GeoJson specifications described in the documentation.

Parameters:

lineStrings - a list of LineStrings which make up this MultiLineString

Returns:

a new instance of this class defined by the values passed inside this static factory method

Since:

3.0.0

fromLineStrings

public static MultiLineString fromLineStrings(@NonNull
