Class EdgeElement

java.lang.Object
  uk.ac.bbk.dcs.automed.hdmstore.EdgeElement

public class EdgeElement
extends java.lang.Object

An edge element represents a single element of an edge. Static methods exist to convert between lists of edge elements and the ASG class used to represent queries in AutoMed. (In retrospect this class should have been combined with Span
