public DiffList()

Method Details

computeFirstList

public List<T> computeFirstList()

Compute and return the source text (all equalities and deletions).

Returns:

Source text.

computeSecondList

public List<T> computeSecondList()

Compute and return the destination text (all equalities and insertions).

Returns:

Destination text.

getLevenshteinDistance

public int getLevenshteinDistance()

Compute the Levenshtein distance; the number of inserted, deleted or substituted characters.

Returns:

translateIndex

public int translateIndex(int loc)

loc is a location in text1, compute and return the equivalent location in text2. e.g. "The cat" vs "The big cat", 1->1, 5->8

Parameters:

loc - Location within text1.

Returns:

Location within text2.
