- org.eclipse.jgit.diff.Edit

```
public class Edit
extends Object
```
A modified region detected between two versions of roughly the same content.
An edit covers the modified region only. It does not cover a common region.
Regions should be specified using 0 based notation, so add 1 to the start and end marks for line numbers in a file.
An edit where beginA == endA && beginB < endB is an insert edit, that is sequence B inserted the elements in region [beginB, endB) at beginA.
An edit where beginA < endA && beginB == endB is a delete edit, that is sequence B has removed the elements between [beginA, endA).
An edit where beginA < endA && beginB < endB is a replace edit, that is sequence B has replaced the range of elements between [beginA, endA) with those found in [beginB, endB).

    Returns:
    
    return length of the region in B
  - shift
```
public final void shift(int amount)
```
    Move the edit region by the specified amount.
    
    Parameters:
    
    amount - the region is shifted by this amount, and can be positive or negative.
    
    Since:
    
    4.8
  - before
```
public final Edit before(Edit cut)
```
    Construct a new edit representing the region before cut.
    
    Parameters:
    
    cut - the cut point. The beginning A and B points are used as the end points of the returned edit.
    
    Returns:
    
    an edit representing the slice of this edit that occurs before cut starts.
  - after
```
public final Edit after(Edit cut)
```
    Construct a new edit representing the region after cut.
    
    Parameters:
    
    cut - the cut point. The ending A and B points are used as the starting points of the returned edit.
    
    Returns:
