Java Utililty Methods Vector from String

String constructFilter(String hostname, Vector schedulertypes)
what is this used for?

StringBuffer filter = new StringBuffer();
filter.append("(&(objectclass=GlobusServiceJobManager)(hn=");
filter.append(hostname);
if (hostname.indexOf("*") == -1)
 filter.append("*");
filter.append(")");
int size = schedulertypes.size();
if (size != 0) {
...

boolean containSource(Vector sources, String source)
contain Source

if (sources == null || sources.size() == 0)
 return false;
String s = null;
for (int i = 0; i < sources.size(); i++) {
 s = (String) sources.elementAt(i);
 if (s.compareTo(source) == 0)
 return true;
return false;

Vector convertStringToVector(String source, String separator)
Convert the passed String into a vector

if (source == null || separator == null) {
 return null;
Vector v = new Vector();
StringTokenizer st = new StringTokenizer(source, separator);
while (st.hasMoreTokens()) {
 v.addElement(st.nextToken().trim());
return v;

double[] createNodeValueVector(final String val)
create Node Value Vector

final StringTokenizer tokr = new StringTokenizer(val, DELIM + ",\"");
return new double[tokr.countTokens()];

Vector getKeyStringAsVector(String keyString, String separator)
Return a vector of strings with one element per key value NOTE: An empty string ("") will be regarded as a value, therefor is StringTokenizer not used.

if (keyString == null) {
 return null;
Vector v = new Vector();
int xb = 0;
int xe = 0;
boolean loop = true;
while (loop) {
...

int getposString(Vector vect_valores, String valor)

Returns the position of the element at the vector, -1 if does not appear

for (int i = 0; i < vect_valores.size(); i++)
 if (vect_valores.elementAt(i).equals(valor))
 return (i);
return (-1);

String getStringFromTokens(Vector vector, String delimiter)
Return a String who contains the strings in the Vector vector separated by delimiter.

int nelem = vector.size();
StringBuffer str_ret = new StringBuffer(nelem * delimiter.length());
for (int i = 0; i < nelem; i++) {
 str_ret.append(vector.elementAt(i));
 if (i < nelem - 1) {
 str_ret.append(delimiter);
return str_ret.toString();

String implode(Vector handler, String separator)
implode, link a vector into a string with a separate string

StringBuffer strbuf = new StringBuffer();
try {
 if (!handler.isEmpty()) {
 int len = handler.size();
 for (int loopi = 0; loopi < len; loopi++) {
 strbuf.append((String) handler.get(loopi));
 if (loopi != len - 1)
 strbuf.append(separator);
...

String implode(Vector strings, char delim)
Create a String from the list of strings provided separated by the delimiter.

StringBuffer buf = new StringBuffer();
for (int i = 0; i < strings.size(); i++) {
 buf.append((String) strings.elementAt(i));
 buf.append(delim);
return buf.toString();

void orderedStringInsert(String key, Vector into)
Insert a String into a vector, maintaing the order.

int lo = 0;
int hi = into.size() - 1;
int idx = -1;
String item = null;
int cmp = 0;
if (hi >= lo) {
 while ((hi - lo) > 1) {
 idx = (hi - lo) / 2 + lo;
...
