Public Methods

Method	Description
BelongsToSameDocumentAs ( ChangeTrackingCheckpoint other ) : bool	Gets whether this checkpoint belongs to the same document as the other checkpoint.
CompareAge ( ChangeTrackingCheckpoint other ) : int	Compares the age of this checkpoint to the other checkpoint. This method is thread-safe.
Create ( TextDocument document ) : ChangeTrackingCheckpoint	Creates a change tracking checkpoint for the specified document. This method is thread-safe. If you need a ChangeTrackingCheckpoint that's consistent with a snapshot of the document, use TextDocument.CreateSnapshot(out ChangeTrackingCheckpoint).
GetChangesTo ( ChangeTrackingCheckpoint other ) : IEnumerable	Gets the changes from this checkpoint to the other checkpoint. If 'other' is older than this checkpoint, reverse changes are calculated. This method is thread-safe.
MoveOffsetTo ( ChangeTrackingCheckpoint other, int oldOffset, AnchorMovementType movement ) : int	Calculates where the offset has moved in the other buffer version. This method is thread-safe.
