Constructor Detail

LineString

public LineString(Point p1,
                  Point p2,
                  Point... pn)

Creates a line string from a series of 2 or more points.

Parameters:

p1 - the first point.

p2 - the second point.

pn - additional points.

Method Detail

fromWellKnownText

public static LineString fromWellKnownText(String source)

Creates a line string from its Well-known Text (WKT) representation.

Parameters:

source - the Well-known Text representation to parse.

Returns:

the line string represented by the WKT.

Throws:

InvalidTypeException - if the string does not contain a valid Well-known Text representation.

fromWellKnownBinary

public static LineString fromWellKnownBinary(ByteBuffer source)

Creates a line string from its Well-known Binary (WKB) representation.

Parameters:

source - the Well-known Binary representation to parse.

Returns:

the line string represented by the WKB.

Throws:

InvalidTypeException - if the provided ByteBuffer does not contain a valid Well-known Binary representation.

fromGeoJson

public static LineString fromGeoJson(String source)

Creates a line string from a GeoJSON LineString representation.

Parameters:

source - the GeoJSON LineString representation to parse.

Returns:

the line string represented by the GeoJSON LineString.

Throws:

InvalidTypeException - if the string does not contain a valid GeoJSON LineString representation.

getPoints

public List<Point> getPoints()

Returns the points composing this line string.

Returns:

the points (as an immutable list).
