Method Detail

getCoordinates

public List<GeoJSONCoordinate> getCoordinates()

setCoordinates

public GeoJSONLineString setCoordinates(List<GeoJSONCoordinate> coordinates)

create

public static GeoJSONLineString create(List<GeoJSONCoordinate> points)

subLineString

public GeoJSONLineString subLineString(int fromIndex,
                                       int toIndex)

Parameters:

fromIndex - low coordinate-pair (inclusive) of the subLineString

toIndex - high coordinate-pair (exclusive) of the subLineString

Returns:

a shallow copy of the requested sub part, i.e. the sublist and the old list are independent from each other but use the same GeoJSONCoordinates

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface GeoJSONGeometryObject

Returns:

true if the element does not contain any coordinates

validate

public void validate()

Description copied from interface: Validatable

Checks if the instance is in a valid / useful state. If this is not the case an IllegalArgumentException including a description of the invalid state is thrown.

Specified by:

validate in interface Validatable

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toWKT

public String toWKT()

Specified by:

toWKT in interface GeoJSONGeometryObject

Returns:

the well known text representation of this geometry object

toString

public String toString()

Overrides:

toString in class Object
