Member Function Documentation

DerivePointAtIndex()

Luciad.Utils.Observable< Luciad.Geometries.Point > Luciad.Geometries.Observable.ObservablePolylineRingUtil.DerivePointAtIndex ( Luciad.Utils.Observable< Luciad.Geometries.PolylineRing >  observablePolylineRing, uint  index  )

inlinestatic

Derives an Observable Point from the given observable polyline ring that represents the point at the given index.

This observable point will be updated when the given observable polyline ring changes. Notes: When the observable polyline ring contains a nullptr value, the observable point instance will contain a nullptr value too. When the given index >= point count, the observable point instance will contain a nullptr value. Observable::setValue will throw an exception for derived instances.

observablePolylineRing

an observable polyline ring from which to derive the point

index

the point index

a derived Observable

DerivePointOnSegment()

Luciad.Utils.Observable< Luciad.Geometries.Point > Luciad.Geometries.Observable.ObservablePolylineRingUtil.DerivePointOnSegment ( Luciad.Utils.Observable< Luciad.Geometries.PolylineRing >  observablePolylineRing, uint  segmentIndex, double  parameter  )

inlinestatic

Derives an Observable Point from the given observable polyline ring that represents a point on a segment of the polyline ring.

This observable point will be updated when the given observable polyline ring changes. Notes: When the observable polyline ring contains a nullptr value, the observable point instance will contain a nullptr value too. When the given segmentIndex >= point count, the observable point instance will contain a nullptr value. Observable::setValue will throw an exception for derived instances.

observablePolylineRing

an observable polyline ring from which to derive the point

segmentIndex

a segment index: a value between [0, pointCount - 2]. For example: segment index 0 corresponds with the segment between the points with index 0 and 1.

parameter

a parameter value between [0, 1] that determines which point of the segment is chosen. This can for example be 0.5, to get the middle of the segment
