Class VersionedFile

    java.lang.Object

public class VersionedFile

Represents one versioned file in the `Repository`, including its name, `Directory` and `Revision` list. Revisions can be created using the `addXXXRevision` factory methods. Revisions can be created in any order. TODO: Rename class to something like VersionedFile, getCurrentLinesOfCode() to getCurrentLines(), maybe getFilenameXXX, isDead() to isDeleted()
