Class RosterSpeedProfile

java.lang.Object

jmri.jmrit.roster.RosterSpeedProfile

public class RosterSpeedProfile
extends java.lang.Object

A simple class to store a speed profile for a given loco The speed steps against the profile are on a scale of 0 to 1000, this equates to the float speed x 1000. This allows a single profile to cover different throttle speed step settings. So a profile generate for a loco using 28 steps can be used for a throttle using 126 steps.
