public final class StringUtils

extends java.lang.Object

This class contains String utilities. The code was taken from Apache Commons, LANG project. Reason is to provide an alternate method to java.lang.String.replace(). That method uses java.util.regex.Pattern.matcher(), which has a PERF issue.

Method Summary

static java.lang.String	join(java.util.Iterator iterator, char separator) Joins the elements of the provided Iterator into a single String containing the provided elements.
static java.lang.String	join(java.lang.Object[] array, char separator) Joins the elements of the provided array into a single String containing the provided list of elements.
static java.lang.String	replace(java.lang.String text, java.lang.String searchString, java.lang.String replacement)

Method Detail

replace

public static java.lang.String replace(java.lang.String text,
                                       java.lang.String searchString,
                                       java.lang.String replacement)

join

public static java.lang.String join(java.lang.Object[] array,
                                    char separator)

Joins the elements of the provided array into a single String containing the provided list of elements.

No delimiter is added before or after the list. Null objects or empty strings within the array are represented by empty strings.

 StringUtils.join(null, *) = null
 StringUtils.join([], *) = ""
 StringUtils.join([null], *) = ""
 StringUtils.join(["a", "b", "c"], ';') = "a;b;c"
 StringUtils.join(["a", "b", "c"], null) = "abc"
 StringUtils.join([null, "", "a"], ';') = ";;a"
 

Parameters:

array - the array of values to join together, may be null

separator - the separator character to use

Returns:

the joined String, null if null array input

                                    char separator)

Joins the elements of the provided Iterator into a single String containing the provided elements.
