Enclosing class:

GitPositionTransformer
```
public abstract static class GitPositionTransformer.FileMapping
extends Object
```
A mapping of attributes from a file in one Git tree (source) to a file in another Git tree (target).
At the moment, only the file path is considered. Other attributes like file mode would be imaginable too but are currently not supported.

- Method Detail
  - oldPath
```
public abstract Optional<String> oldPath()
```
    File path in the source tree. For file additions, this is an empty Optional.
  - newPath
```
public abstract Optional<String> newPath()
```
    File path in the target tree. Can be the same as oldPath() if unchanged. For file deletions, this is an empty Optional.
  - forAddedFile
```
public static GitPositionTransformer.FileMapping forAddedFile(String filePath)
```
    Creates a GitPositionTransformer.FileMapping for a file addition.
    In the context of GitPositionTransformer, file additions are irrelevant as no given position in the source tree can refer to such a new file in the target tree. We still provide this factory method so that code outside of GitPositionTransformer doesn't have to care about such details and can simply create GitPositionTransformer.FileMappings for any modifications between the trees.
  - forDeletedFile
```
public static GitPositionTransformer.FileMapping forDeletedFile(String filePath)
```
    Creates a GitPositionTransformer.FileMapping for a file deletion.
  - forModifiedFile
```
public static GitPositionTransformer.FileMapping forModifiedFile(String filePath)
```
    Creates a GitPositionTransformer.FileMapping for a file modification.
  - forRenamedFile
```
public static GitPositionTransformer.FileMapping forRenamedFile(String oldPath,
                                                                String newPath)
```
    Creates a GitPositionTransformer.FileMapping for a file renaming.
  - forFile
```
public static GitPositionTransformer.FileMapping forFile(Optional<String> oldPath,
                                                         Optional<String> newPath)
```
    Creates a GitPositionTransformer.FileMapping using the old and new paths.
