Method Detail

create

public static LengthsParameters create()

Creates a new LengthsParameter object.

Returns:

LengthsParameters

isGeodesic

public final boolean isGeodesic()

If polylines are in geographic coordinate system, then geodesic needs to be set to true in order to calculate the ellipsoidal shortest path distance between each pair of the vertices in the polylines. The output if lengthUnit if not specified is returned in meters.

Returns:

boolean

setGeodesic

public final void setGeodesic(boolean geodesic)

Set the geodesic parameter

Parameters:

geodesic - - If polylines are in geographic coordinate system, then geodesic needs to be set to true in order to calculate the ellipsoidal shortest path distance between each pair of the vertices in the polylines. The output if lengthUnit if not specified is returned in meters.

getLengthUnit

public final GeometryService.UnitType getLengthUnit()

The length unit in which perimeters of polygons will be calculated. It can be any esriUnits constant. If unit is not specified, the units are derived from sr

Returns:

UnitType

setLengthUnit

public final void setLengthUnit(GeometryService.UnitType lengthUnit)

Set the length unit parameter.

Parameters:

lengthUnit - - The length unit in which perimeters of polygons will be calculated. It can be any esriUnits constant. If unit is not specified, the units are derived from sr

getPolylines

public final com.google.gwt.core.client.JsArray<Geometry> getPolylines()

The array of polylines whose lengths are to be computed. The spatial reference of the polylines is specified by sr. The structure of each polyline in the array is same as the structure of the JSON polyline objects returned by the ArcGIS REST API.

Returns:

JsArray

setPolylines

public final void setPolylines(Geometry[] polylines)

Set the polylines parameter.

Parameters:

polylines - - The array of polylines whose lengths are to be computed. The spatial reference of the polylines is specified by sr. The structure of each polyline in the array is same as the structure of the JSON polyline objects returned by the ArcGIS REST API.
