Method

Stringjoin(Iterable list, String delimiter)
Joins the Strings of the provided array into a single String. 
if (list == null) {
    return "";
StringBuilder builder = new StringBuilder();
Iterator<String> iter = list.iterator();
while (iter.hasNext()) {
    builder.append(iter.next());
    if (!iter.hasNext()) {
...
Listjoin(List a, List b)
Used by common.ext. 
List l = new ArrayList();
if (a != null) {
    l.addAll(a);
if (b != null) {
    l.addAll(b);
return l;
...
Stringjoin(List a_quotedArgs)
join 
StringBuffer joined = new StringBuffer();
int quotedSize = a_quotedArgs.size();
for (int index = 0; index < quotedSize; index++) {
    if (index > 0) {
        joined.append(' ');
    joined.append(a_quotedArgs.get(index));
return joined.toString();
Stringjoin(List array, String separator)
join 
if (array == null) {
    return null;
if (separator == null) {
    separator = EMPTY;
StringBuffer buf = new StringBuffer();
for (int i = 0; i < array.size(); i++) {
...
Stringjoin(List elements, String joinWith)
join 
if (elements == null || elements.size() == 0)
    return null;
StringBuilder buffer = new StringBuilder(56);
for (Iterator i$ = elements.iterator(); i$.hasNext(); buffer.append(joinWith)) {
    String str = (String) i$.next();
    buffer.append(str);
return buffer.toString();
...
Stringjoin(List elements, String sep)
"join" a List of Strings into a single string, with each string separated by a defined separator string. 
StringBuffer sb = new StringBuffer();
boolean first = true;
Iterator iter = elements.iterator();
while (iter.hasNext()) {
    String element = (String) iter.next();
    if (!first) {
        sb.append(sep);
    } else {
...
Stringjoin(List items, String separator)
join 
StringBuilder sb = new StringBuilder();
for (int i = 0; i < items.size(); i++) {
    boolean lastItem = i == items.size() - 1;
    sb.append(items.get(i));
    if (!lastItem) {
        sb.append(separator);
return sb.toString();
Stringjoin(List l, String sep)
join 
String[] fields = (String[]) l.toArray(new String[l.size()]);
return join(fields, sep);
Stringjoin(List list, char separator)
join 
if (list == null) {
    return "";
int size = list.size();
if (size == 0) {
    return "";
if (size == 1) {
...
Stringjoin(List list, String delim)
join 
if (list == null || list.size() < 1)
    return null;
StringBuffer buf = new StringBuffer();
Iterator i = list.iterator();
while (i.hasNext()) {
    buf.append((String) i.next());
    if (i.hasNext())
        buf.append(delim);
