Method Detail

getLevenshteinDistance

public static int getLevenshteinDistance(String s,
                                         String t,
                                         int maxAllowedEditDistance)

Efficient version of Levenshtein Distance Algorithm. It saves CPU by returning early if the distance goes over maxAllowedEditDistance. See examples in LevenshteinDistanceTest class.

Parameters:

s - String

t - String

maxAllowedEditDistance - int

Returns:

min(LD(s, t), maxAllowedEditDistance + 1)
