- Method Detail
  - indexOf
```
int indexOf(Step step)
```
    Gets the index of the given step.
    
    Parameters:
    
    step - the step to get the index of
    
    Returns:
    
    the index of the given step, or -1 if this object does not contain that step
  - compare
```
default int compare(Step o1,
                    Step o2)
```
    Compares two steps based on their indexes. This is not consistent with equals().
    
    Specified by:
    
    compare in interface java.util.Comparator<Step>
    
    Parameters:
    
    o1 - the first step to compare
    
    o2 - the second step to compare
