Methods Summary
static java.lang.String	clean(java.lang.String str) Cleans up the input string before Soundex processing by only returning upper case letters. param str The String to clean. return A clean String. if (str == null || str.length() == 0) { return str; } int len = str.length(); char[] chars = new char[len]; int count = 0; for (int i = 0; i < len; i++) { if (Character.isLetter(str.charAt(i))) { chars[count++] = str.charAt(i); } } if (count == len) { return str.toUpperCase(); } return new String(chars, 0, count).toUpperCase();
static int	difference(org.apache.commons.codec.StringEncoder encoder, java.lang.String s1, java.lang.String s2) Encodes the Strings and returns the number of characters in the two encoded Strings that are the same. For Soundex, this return value ranges from 0 through 4: 0 indicates little or no similarity, and 4 indicates strong similarity or identical values. For refined Soundex, the return value can be greater than 4. param encoder The encoder to use to encode the Strings. param s1 A String that will be encoded and compared. param s2 A String that will be encoded and compared. return The number of characters in the two Soundex encoded Strings that are the same. see #differenceEncoded(String,String) see MS T-SQL DIFFERENCE throws EncoderException if an error occurs encoding one of the strings return differenceEncoded(encoder.encode(s1), encoder.encode(s2));
static int	differenceEncoded(java.lang.String es1, java.lang.String es2) Returns the number of characters in the two Soundex encoded Strings that are the same. For Soundex, this return value ranges from 0 through 4: 0 indicates little or no similarity, and 4 indicates strong similarity or identical values. For refined Soundex, the return value can be greater than 4. param es1 An encoded String. param es2 An encoded String. return The number of characters in the two Soundex encoded Strings that are the same. see MS T-SQL DIFFERENCE if (es1 == null || es2 == null) { return 0; } int lengthToMatch = Math.min(es1.length(), es2.length()); int diff = 0; for (int i = 0; i < lengthToMatch; i++) { if (es1.charAt(i) == es2.charAt(i)) { diff++; } } return diff;
