Class Difference

  • public class Difference
extends java.lang.Object
    Represents a difference, as used in Diff. A difference consists of two pairs of starting and ending points, each pair representing either the "from" or the "to" collection passed to Diff. If an ending point is -1, then the difference was either a deletion or an addition. For example, if getDeletedEnd() returns -1, then the difference represents an addition.
