public final class StringW

extends java.lang.Object

A set of String library static methods. While extending String or StringBuffer would have been the nicest solution, that is not possible, so a simple set of static methods seems the most workable. Most methods have now gone to Commons Lang StringUtils. Method ideas have so far been taken from the PHP4, Ruby and .NET languages.

static java.lang.String	join(java.lang.Object[] objs, java.lang.String sep, java.lang.String pre, java.lang.String post)
static java.lang.String	quoteRegularExpression(java.lang.String str) Deprecated. Useless as it doesn't handle character classes and I never use it. Gone in 3.0.

join

public static java.lang.String join(java.lang.Object[] objs,
                                    java.lang.String sep,
                                    java.lang.String pre,
                                    java.lang.String post)

getLevenshteinDistance

public static int getLevenshteinDistance(java.lang.String s,
                                         java.lang.String t)

Deprecated. in favour of Commons Codec

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. This implemmentation of the levenshtein distance algorithm is from http://www.merriampark.com/ld.htm

quoteRegularExpression

public static java.lang.String quoteRegularExpression(java.lang.String str)

Deprecated. Useless as it doesn't handle character classes and I never use it. Gone in 3.0.

Quote a string so that it may be used in a regular expression without any parts of the string being considered as a part of the regular expression's control characters.

wordWrap

public static java.lang.String wordWrap(java.lang.String str)

Create a word-wrapped version of a String. Wrap at 80 characters and use newlines as the delimiter. If a word is over 80 characters long use a - sign to split it.

wordWrap

public static java.lang.String wordWrap(java.lang.String str,
                                        int width)

Create a word-wrapped version of a String. Wrap at a specified width and use newlines as the delimiter. If a word is over the width in lenght use a - sign to split it.

wordWrap

public static java.lang.String wordWrap(java.lang.String str,
                                        java.lang.String width,
                                        java.lang.String delim,
                                        java.lang.String split)

wordWrap

public static java.lang.String wordWrap(java.lang.String str,
                                        int width,
                                        java.lang.String delim,
                                        java.lang.String split)

Word-wrap a string.

Parameters:

str - String to word-wrap

width - int to wrap at

delim - String to use to separate lines

split - String to use to split a word greater than width long

Returns:

String that has been word wrapped
