public abstract class AbstractThrottle

implements DccThrottle
```
An abstract implementation of DccThrottle. Based on Glen Oberhauser's original LnThrottleManager implementation.
Note that this implements DccThrottle, not Throttle directly, so it has some DCC-specific content.

```
public void dispatch(ThrottleListener l)
```
    Finished with this Throttle, tell the layout that the locomotive is available for reuse/reallocation by somebody else.

    dispatch in interface Throttle
    
    Parameters:
    
    l - ThrottleListener to dispatch
  - release
```
public void release(ThrottleListener l)
```
    Finished with this Throttle, tell the layout that the locomotive is available for reuse/reallocation by somebody else.

    Normally, release ends with a call to dispose.
    
    Specified by:
    
    release in interface Throttle

    l - ThrottleListener to release. May be null if no ThrottleListener is currently held.

    Specified by:
    
    setSpeedStepMode in interface DccThrottle
    
    Parameters:
    
    mode - the current speed step mode
  - getSpeedStepMode
```

```
    Description copied from interface: DccThrottle
    
    Get the current speed step value.
    
    Specified by:
    
    getSpeedStepMode in interface DccThrottle
    
    Returns:
    
    the current speed step mode

    Processes updated speed from subclasses. Tracks total operating time for the roster entry by starting the clock if speed is non-zero or stopping the clock otherwise.
    
    Parameters:
    
    speed - the current speed
  - startClock
```
protected void startClock()
```
  - stopClock
```
void stopClock()
```
  - finishRecord

protected int intSpeed(float speed)
```
    Get an integer speed for the given raw speed value. This is a convenience method that calls intSpeed(float, int) with a maxStep of 127.
    
    Parameters:
    
    speed - the speed as a percentage of maximum possible speed; negative values indicate a need for an emergency stop
    
    Returns:
    
    an integer in the range 0-127
  - intSpeed
```
protected static int intSpeed(float speed,
                              int steps)
```
    Get an integer speed for the given raw speed value.
    
    Parameters:
    
    speed - the speed as a percentage of maximum possible speed; negative values indicate a need for an emergency stop
    
    steps - number of possible speeds; values less than 2 will cause errors
    
    Returns:
    
    an integer in the range 0-steps
