Class TrackMoveTransactionsGenerator

java.lang.Object
  jfreerails.move.TrackMoveTransactionsGenerator

public class TrackMoveTransactionsGenerator
extends java.lang.Object

This class calculates the cost of a series of track moves. The motivation for separating this code from the code that generates track moves is that the transactions will be generated by the server whereas the track moves will be generated by a client.
