Class Edge

java.lang.Object
  edu.isi.pegasus.planner.provisioner.Edge

public class Edge
extends Object

An instance of this class represent an edge of workflow which is data dependencies between two tasks. So this class contains references of two dependent nodes(From node and To node) and information of data between them; file name, data size and data transfer time.
