Class DiffRowGenerator

java.lang.Object
  difflib.DiffRowGenerator

public class DiffRowGenerator
extends Object

This class for generating DiffRows for side-by-sidy view. You can customize the way of generating. For example, show inline diffs on not, ignoring white spaces or/and blank lines and so on. All parameters for generating are optional. If you do not specify them, the class will use the default values. These values are: showInlineDiffs = false; ignoreWhiteSpaces = true; ignoreBlankLines = true; ... For instantiating the DiffRowGenerator you should use the its builder. Like in example DiffRowGenerator generator = new DiffRowGenerator.Builder().showInlineDiffs(true). ignoreWhiteSpaces(true).columnWidth(100).build();
