DatabaseRenderer

public DatabaseRenderer(MapDataStore mapDataStore,
                        org.mapsforge.core.graphics.GraphicFactory graphicFactory,
                        TileCache tileCache,
                        TileBasedLabelStore labelStore,
                        boolean renderLabels,
                        boolean cacheLabels,
                        HillsRenderConfig hillsRenderConfig)

Constructs a new DatabaseRenderer. There are three possible configurations: 1) render labels directly onto tiles: renderLabels == true && tileCache != null 2) do not render labels but cache them: renderLabels == false && labelStore != null 3) do not render or cache labels: renderLabels == false && labelStore == null

Parameters:

mapDataStore - the data source.

graphicFactory - the graphic factory.

tileCache - where tiles are cached (needed if labels are drawn directly onto tiles, otherwise null)

labelStore - where labels are cached.

renderLabels - if labels should be rendered.

cacheLabels - if labels should be cached.

hillsRenderConfig - the hillshading setup to be used (can be null).
