| RangeDifference | | public class RangeDifference (Code) | | Description of a change between two or three ranges of comparable entities.
RangeDifference objects are the elements of a compare result returned from
the RangeDifferencer find* methods.
Clients use these objects as they are returned from the differencer.
This class is not intended to be instantiated or subclassed outside of the Compare framework.
Note: A range in the RangeDifference object is given as a start index
and length in terms of comparable entities. However, these entity indices and counts
are not necessarily character positions. For example, if an entity represents a line
in a document, the start index would be a line number and the count would be in lines.
