com.here.platform.location.inmemory.graph.TiledEdgePropertyMap<T,U>

All Implemented Interfaces:

com.here.platform.location.core.graph.PropertyMap<Edge,U>

Direct Known Subclasses:

TiledEdgePropertyMap.Identity

public abstract class TiledEdgePropertyMap<T,U>
extends Object
implements com.here.platform.location.core.graph.PropertyMap<Edge,U>

A PropertyMap[Edge, T] that retrieves edge attribute values from multiple EdgePropertyTiles.

For a given edge, TiledEdgePropertyMap first uses tileById to retrieve the propertyTile that has the same tile ID as the Edge source Vertex. Then, TiledEdgePropertyMap retrieves the attribute value from this EdgePropertyTile by calling propertyTile.values(edge.index.value).

If, for a given tile ID, the mapping function returns an EdgePropertyTile that has a different tile ID, apply throws a RuntimeException.

param: tileById Used to retrieve a data tile by its ID, if it exists
