## Class Revision

- java.lang.Object
- - net.sf.statcvs.model.Revision

All Implemented Interfaces:
  java.lang.Comparable

    public class Revision
    extends java.lang.Object
    implements java.lang.Comparable

One revision of a `VersionedFile`. That can be an initial revision (checkin), a change, a deletion, or a re-add. Revisions are created using the methods `VersionedFile.addInitialRevision(java.lang.String, net.sf.statcvs.model.Author, java.util.Date, java.lang.String, int, java.util.SortedSet)`, `VersionedFile.addChangeRevision(java.lang.String, net.sf.statcvs.model.Author, java.util.Date, java.lang.String, int, int, int, java.util.SortedSet)` and `VersionedFile.addDeletionRevision(java.lang.String, net.sf.statcvs.model.Author, java.util.Date, java.lang.String, int, java.util.SortedSet)`. TODO: Replace type code with hierarchy TODO: Rename class to Revision, getAuthor() to getLogin(), isDead() to isDeletion()

### Field Detail

#### TYPE_CREATION

    public static final int TYPE_CREATION

Marks a revision that creates a new file. The file did not exist in the current branch before this revision, and it does exist afterwards. Possibly the file existed before, that is, it was deleted and restored.

See Also:
  Constant Field Values

#### TYPE_CHANGE

    public static final int TYPE_CHANGE

Marks a revision that changes the file. It does neither create nor delete the file.

See Also:
  Constant Field Values

#### TYPE_DELETION

    public static final int TYPE_DELETION

Marks a revision that deletes the file. The file existed before, but does not exist afterwards in the current branch.

See Also:
  Constant Field Values

#### TYPE_BEGIN_OF_LOG

    public static final int TYPE_BEGIN_OF_LOG

Marks a revision at the very beginning of the log timespan. This is only a container for the number of code lines at the beginning of the log. It is not a real revision committed by an author.

See Also:
  Constant Field Values

### Constructor Detail

#### Revision

    public Revision(VersionedFile file,
            java.lang.String revisionNumber,
            int type,
            Author author,
            java.util.Date date,
            java.lang.String comment,
            int lines,
            int linesDelta,
            int linesReplaced,
            java.util.SortedSet symbolicNames)

Creates a new revision of a file with the specified revision number. Should not be called directly. Instead, `VersionedFile.addInitialRevision(java.lang.String, net.sf.statcvs.model.Author, java.util.Date, java.lang.String, int, java.util.SortedSet)` and its sister methods should be used.

Parameters:
  `file` - VersionedFile that belongs to this revision
  `revisionNumber` - revision number, for example "1.1"
  `type` - a `TYPE_XXX` constant
  `author` - the author of the revision
  `date` - the date of the revision
  `comment` - the author's comment
  `lines` - number of lines; 0 for deletions
  `linesDelta` - by how much did the number of lines change, compared to the previous revision?
  `linesReplaced` - How many lines were removed and replaced by other lines, without the delta changing?
  `symbolicNames` - list of symbolic names for this revision or null if this revision has no symbolic names

### Method Detail
