| DiffUtil | | public class DiffUtil (Code) | | View Source
This class can compare two different versions of a text. Source refers to
the earliest version of the text and target refers to a modified version of
source. Changes are considered either as a removal from the source or as an
addition to the target. This class detects changes to an entire line and also
detects changes within lines, such as, removal or addition of characters.
Take a look at DiffTest to see the expected inputs and outputs.
