getLevenshteinDistance

public static int getLevenshteinDistance(String s,
                                         String t)

Deprecated.

Find the Levenshtein distance between two Strings.

This is the number of changes needed to change one String into another, where each change is a single character modification (deletion, insertion or substitution).

The previous implementation of the Levenshtein distance algorithm was from http://www.merriampark.com/ld.htm

Chas Emerick has written an implementation in Java, which avoids an OutOfMemoryError which can occur when my Java implementation is used with very large strings.
This implementation of the Levenshtein distance algorithm is from http://www.merriampark.com/ldjava.htm

 StringUtil.getLevenshteinDistance(null, *)             = IllegalArgumentException
 StringUtil.getLevenshteinDistance(*, null)             = IllegalArgumentException
 StringUtil.getLevenshteinDistance("","")               = 0
 StringUtil.getLevenshteinDistance("","a")              = 1
 StringUtil.getLevenshteinDistance("aaapppp", "")       = 7
 StringUtil.getLevenshteinDistance("frog", "fog")       = 1
 StringUtil.getLevenshteinDistance("fly", "ant")        = 3
 StringUtil.getLevenshteinDistance("elephant", "hippo") = 7
 StringUtil.getLevenshteinDistance("hippo", "elephant") = 7
 StringUtil.getLevenshteinDistance("hippo", "zzzzzzzz") = 8
 StringUtil.getLevenshteinDistance("hello", "hallo")    = 1
 

Parameters:

s - the first String, must not be null

t - the second String, must not be null

Returns:

result distance

Throws:

IllegalArgumentException - if either String input null

lookup

public static <T extends Enum<?>> T lookup(Map<String,T> lookup,
                                           String name,
                                           boolean fuzzy)

Deprecated.
