abstract class TiledEdgePropertyMap[T, U] extends 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.

Abstract Value Members

  1. abstract def transform(value: T): U

    Converts the value of a property from its representation inside the underlying EdgePropertyTile to the form that will be returned to the user.

    Converts the value of a property from its representation inside the underlying EdgePropertyTile to the form that will be returned to the user.

    This transformation will be applied every time a value is retrieved and its results will not be cached. For this reason, this method should be as fast as possible.

  8. def default(edge: Edge): U

    Specifies how to handle missing tiles.

    Specifies how to handle missing tiles.

    If tileById returns None for a specific tile ID, the tile is missing, which means that there is no data available.

    This method lets you tune how this is interpreted.

    The default implementation is to throw NoSuchElementException, meaning that trying to access the data of such a tile is an error.

    For some properties the missing tile should be interpreted as if all values in the tile are the same default value, depending on the semantics of the property. For example, a missing tile that describes permitted turns for a given edge, might mean that all turns are permitted for all vehicle types. In that case, override this method to provide that default value.
