public abstract ListDiffEntry[] getDifferences()
public void accept(ListDiffVisitor visitor)
getDifferences() array, calling the appropriate
method in visitor for each difference.
ListDiffVisitor.handleReplace(int, Object, Object) is called
whenever an add entry is adjacent to a remove entry, and both entries
operate on the same location in the list.
ListDiffVisitor.handleMove(int, int, Object) is called
whenever an add entry is adjacent to a remove entry, and both entries
have equivalent elements.
ListDiffVisitor.handleRemove(int, Object) is called whenever
a remove entry does not match conditions 1 or 2.
ListDiffVisitor.handleAdd(int, Object) is called whenever an
add entry does not match conditions in 1 or 2.
