public interface EditComparator<T>
```
Interface for comparators between elements.
This interface uses EditStep both for convenience, and also to allow the possibility of an edit operation having both EditStep.getStepDistance() = 0 and EditStep.getOperation() is set to either EditStep.StepOperation.CHANGE. This allows for non-equal elements to have zero distance, but still preserve the fact of their inequality.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`EditStep<T>`	`compare(T from, T to)`	Compares two sequence elements, and evaluates the distance between them.
`EditStep<T>`	`delete(T from)`	The distance for deleting the given element.
`EditStep<T>`	`insert(T to)`	The distance for inserting the given element.

- Method Detail
  - compare
```
EditStep<T> compare(T from,
                    T to)
```
    Compares two sequence elements, and evaluates the distance between them.
    
    Parameters:
    
    from - The element from the source sequence, which may be null,
    
    to - The element from the destination sequence, which may be null.
    
    Returns:
    
    An edit step between the two elements. EditStep.getFrom() is set to from, EditStep.getTo() is set to to, EditStep.getStepDistance() is set to the computed edit distance between these two elements, and EditStep.getOperation() is set to either EditStep.StepOperation.NONE or EditStep.StepOperation.CHANGE.
  - delete
```
EditStep<T> delete(T from)
```
    The distance for deleting the given element.
    
    Parameters:
    
    from - The element that would be deleted, which may be null.
    
    Returns:
    
    An edit step with EditStep.getStepDistance() set to the distance for deleting the given element. EditStep.getFrom() is set to from, and EditStep.getOperation() is set to EditStep.StepOperation.DELETE
  - insert
```
EditStep<T> insert(T to)
```
    The distance for inserting the given element.
    
    Parameters:
    
    to - The element that would be inserted, which may be null.
    
    Returns:
    
    An edit step with EditStep.getStepDistance() set to the distance for inserting the given element. EditStep.getTo() is set to to, and EditStep.getOperation() is set to EditStep.StepOperation.INSERT
