    • comparisonType

      public abstract ComparisonType comparisonType()
      Comparison type of old and new commits: against another patchset, parent or auto-merge.

    • oldPath

      public abstract Optional<String> oldPath()
      The file path at the old commit. Returns an empty Optional if changeType() is equal to Patch.ChangeType.ADDED.

    • newPath

      public abstract Optional<String> newPath()

    • getDefaultPath

      public String getDefaultPath()

    • oldMode

      public abstract Optional<Patch.FileMode> oldMode()
      The file mode of the old file at the old git tree diff identified by oldCommitId() ()}.

    • newMode

      public abstract Optional<Patch.FileMode> newMode()
      The file mode of the new file at the new git tree diff identified by newCommitId() ()}.

    • changeType

      public abstract Patch.ChangeType changeType()
      The change type of the underlying file, e.g. added, deleted, renamed, etc...

    • patchType

      public abstract Optional<Patch.PatchType> patchType()
      The patch type of the underlying file, e.g. unified, binary , etc...

    • headerLines

      public abstract com.google.common.collect.ImmutableList<String> headerLines()
      A list of strings representation of the header lines of the FileHeader that is produced as output of the diff.

    • edits

      public abstract com.google.common.collect.ImmutableList<TaggedEdit> edits()
      The list of edits resulting from the diff hunks of the file.

    • size

      public abstract long size()
      The file size at the new commit.

    • sizeDelta

      public abstract long sizeDelta()
      Difference in file size between the old and new commits.

    • negative

      public abstract Optional<Boolean> negative()
      Returns true if the diff computation was not able to compute a diff, i.e. for diffs taking a very long time to compute. We cache negative result in this case.

    • toBuilder

      public abstract FileDiffOutput.Builder toBuilder()

    • allEditsDueToRebase

      public boolean allEditsDueToRebase()
      A boolean indicating if all underlying edits of the file diff are due to rebase.

    • insertions

      public int insertions()
      Returns the number of inserted lines for the file diff.

    • deletions

      public int deletions()
      Returns the number of deleted lines for the file diff.

    • empty

      public static FileDiffOutput empty(String filePath, org.eclipse.jgit.lib.ObjectId oldCommitId, org.eclipse.jgit.lib.ObjectId newCommitId)
      Returns an entity representing an unchanged file between two commits.

    • createNegative

      public static FileDiffOutput createNegative(String filePath, org.eclipse.jgit.lib.ObjectId oldCommitId, org.eclipse.jgit.lib.ObjectId newCommitId)
      Create a negative file diff. We use this to cache negative diffs for entries that result in timeouts.

    • isEmpty

      public boolean isEmpty()
      Returns true if this entity represents an unchanged file between two commits.

    • isNegative

      public boolean isNegative()
      Returns true if the diff computation was not able to compute a diff. We cache negative result in this case.
