Class TagElevationCalculator

Object
  TagElevationCalculator

All Implemented Interfaces:

ElevationCalculator

Direct Known Subclasses:

BridgeTunnelElevationCalculator, EleTagElevationCalculator, LevelTagElevationCalculator

public abstract class TagElevationCalculator
extends Object
implements ElevationCalculator

relies on tags that explicitly set elevation. Subclasses determine the tag(s) to be used for this purpose.

Constructor Summary

TagElevationCalculator()

TagElevationCalculator(Double terrainElevation, boolean enableUnknownEleWarning)

Method Summary

void	calculateElevations(MapData mapData, CellularTerrainElevation eleData) provides elevation information for all elements in the MapData.
protected abstract Double	getEleForTags(TagGroup tags) returns the elevation as set explicitly by the tags

Constructor Detail

TagElevationCalculator

public TagElevationCalculator(Double terrainElevation,
                              boolean enableUnknownEleWarning)

Parameters:

terrainElevation - elevation for the terrain

Method Detail

calculateElevations

public void calculateElevations(MapData mapData,
                                CellularTerrainElevation eleData)

Description copied from interface: ElevationCalculator

provides elevation information for all elements in the MapData. Implementations of this method need to

• set ElevationProfiles for all MapElements
• determine elevation of all TerrainPoints with unknown elevation by using TerrainPoint.setEle(float).

Specified by:

calculateElevations in interface ElevationCalculator

Parameters:

mapData - map data without elevation profiles; != null

eleData - terrain elevation data, possibly with points with unknown information; whether null is allowed depends on the implementation

getEleForTags

protected abstract Double getEleForTags(TagGroup tags)

returns the elevation as set explicitly by the tags

Returns:

elevation; null if the tags don't define the elevation
