Method

StringstringSubstitution(String argStr, Hashtable vars)
string Substitution 
StringBuffer argBuf = new StringBuffer();
for (int cIdx = 0; cIdx < argStr.length();) {
    char ch = argStr.charAt(cIdx);
    switch (ch) {
    case '$':
        StringBuffer nameBuf = new StringBuffer();
        for (++cIdx; cIdx < argStr.length(); ++cIdx) {
            ch = argStr.charAt(cIdx);
...
Stringsubstitute(String original, String match, String subst)
Find all occurences of the "match" in original, and substitute the "subst" string. 
String s = original;
int pos;
while (0 <= (pos = s.indexOf(match))) {
    StringBuffer sb = new StringBuffer(s);
    s = sb.replace(pos, pos + match.length(), subst).toString();
return s;
Stringsubstitute(String str, Hashtable vars, String delimiter)
Searches the line for any variables which should be substituted with values from the hashtable. 
String key = null;
for (Enumeration keys = vars.keys(); keys.hasMoreElements();) {
    key = (String) keys.nextElement();
    if ((key != null) && (key.indexOf(delimiter) == -1)) {
        str = replaceVar(str, delimiter + key + delimiter, (String) vars.get(key));
return str;
...
StringsubstituteProperty(String value, Properties coreProperties)
substitute Property 
if (value == null || value.indexOf('$') == -1) {
    return value;
List<String> fragments = new ArrayList<String>();
List<String> propertyRefs = new ArrayList<String>();
parsePropertyString(value, fragments, propertyRefs);
StringBuilder sb = new StringBuilder();
Iterator<String> i = fragments.iterator();
