Examples of RangeDifference

com.alkacon.diff.rangedifferencer.RangeDifference
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.
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.
Please note: This class has been modified by Alkacon from the original Eclipse source! The source code has been reformatted and checkstyle / findbugs warnings where removed (AK).

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.
