Member Function Documentation

GetPoint()

Luciad.Cartesian.Coordinate Luciad.Geometries.Polyline.GetPoint ( uint index )

inline

Returns the coordinate for the requested index.

Parameters

index

the index of the requested point.

Returns

the point at the index.

Exceptions

System.ArgumentException

when requesting an invalid index.

InsertPoint()

Luciad.Geometries.Polyline Luciad.Geometries.Polyline.InsertPoint ( uint index, Luciad.Cartesian.Coordinate newLocation )

inline

Creates a new Polyline with an newly inserted control point.

Parameters

index	the index of the newly inserted control point. Should be in [0, {@link Luciad.Geometries.Polyline#PointCount getPointCount()}]. For index 0, a new point will be added at the start of the Polyline. For index getPointCount(), a new point will be added at the end of the Polyline. For other index values, a point will be added between 2 other points.
newLocation	the location of the new point

Returns

a new geometry

Exceptions

System.ArgumentException

for an invalid index

Since

2020.1

MovePoint()

Luciad.Geometries.Polyline Luciad.Geometries.Polyline.MovePoint ( uint index, Luciad.Cartesian.Coordinate newLocation )

inline

Creates a new Polyline with a moved control point.

Parameters

index	the index of the point to move. Should be in [0, {@link Luciad.Geometries.Polyline#PointCount getPointCount()} - 1].
newLocation	the new location of the point

Returns

a new geometry

Exceptions

System.ArgumentException

for an invalid index

Since

2020.1

RemovePoint()

Luciad.Geometries.Polyline Luciad.Geometries.Polyline.RemovePoint ( uint index )

inline

Creates a new Polyline with a control point removed.

This methods returns a copy of the polyline if its point count is less or equal to 2.

Parameters

index

the index of the point to be removed. Should be in [0, {@link Luciad.Geometries.Polyline#PointCount getPointCount()} - 1].

Returns

a new geometry

Exceptions

System.ArgumentException

for an invalid index

Since

2020.1

Translate()

Luciad.Geometries.Polyline Luciad.Geometries.Polyline.Translate ( Luciad.Cartesian.Coordinate translation )

inline

Translates the entire polyline.

Note: when the polyline is defined in a geodetic reference and uses geodetic interpolation, the translation is not performed by translating the points one by one. Instead, a translation method is used that better preserves the shape of the polyline when moving it towards (or away from) the poles.

Parameters

translation

the translation vector

Returns

a new, translated geometry

Since

2020.1

get

The list of points of this polyline.

[get]

Returns the list of points of this polyline.
