Enclosing class:

GitPositionTransformer

public abstract static class GitPositionTransformer.FileMapping

FileMapping

public FileMapping()

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.
