@Deprecated
public interface GraphElement

Many clients of graph methods expect their graph nodes to implement a pair of scratch fields, one of int type and one of object type. This is a fairly evil thing to do, but it is deeply embedded in many places, and this interface can be used for such clients. It is not recommended, to put it mildly.
