Package org.mapsforge.map.layer.hills

Class HillsRenderConfig

java.lang.Object

org.mapsforge.map.layer.hills.HillsRenderConfig

public class HillsRenderConfig
extends java.lang.Object

Mutable frontend for the hillshading cache/processing in HgtCache

All changes are lazily applied when a tile is requested with getShadingTile(int, int, double, double), which includes a full reindex of the .hgt files. Eager indexing on a dedicated thread can be triggered with indexOnThread() (e.g. after a configuration change or during setup)
