org.apache.pig.newplan.OperatorPlan.connect()
Connect two operators in the plan, controlling which position in the edge lists that the from and to edges are placed. @param from Operator edge will come from @param fromPos Position in the array for the from edge @param to Operator edge will go to @param toPos Position in the array for the to edge
