Description

The list of methods to do ID Value Create are organized into topic(s).

Method

StringtoId(String text)
to Id 
return text.replaceAll("[^a-zA-Z0-9\\-_]*", "");
StringtoIdableName(String xpath)
to Idable Name 
xpath = "X" + xpath;
xpath = xpath.replace("/", "-");
xpath = xpath.replace("[", "_");
return xpath.replace("]", ":");
StringtoIdentifier(String input)
Modifies all characters which are not valid in an identifier; leading and trailing blanks are removed. 
final String ti = input.trim();
if (ti.isEmpty() == true) {
    return ti;
final StringBuilder sb = new StringBuilder(ti);
char c = sb.charAt(0);
if (Character.isJavaIdentifierStart(c) == false || c == '$') {
    sb.setCharAt(0, '_');
...
StringtoIdentifier(String name)
convert a name to Java-compatible identifier name. 
return xmlNameToJavaName("field", name);
voidtoIdentifier(String name, StringBuffer fieldName)
to Identifier 
for (int i = 0; i < name.length(); i++) {
    if (name.charAt(i) == ' ')
        fieldName.append(Character.toUpperCase(name.charAt(++i)));
    else
        fieldName.append(name.charAt(i));
StringtoIdentifier(String str)
Given a string, returns a proper C identifier. 
StringBuffer buf = new StringBuffer();
if (!str.isEmpty()) {
    char first = str.charAt(0);
    if (Character.isJavaIdentifierPart(first) && !Character.isJavaIdentifierStart(first)) {
        buf.append("_");
    for (int i = 0; i < str.length(); i++) {
        char ch = str.charAt(i);
...
StringtoIdentifier(String text)
to Identifier 
String out = "";
if (Character.isDigit(text.charAt(0)))
    out += "_";
for (int i = 0; i < text.length(); i++) {
    if (Character.isJavaIdentifierPart(text.charAt(i)))
        out += text.charAt(i);
    else if (text.charAt(i) == ' ')
        out += "_";
...
StringtoIdentifierString(long val)
creates a shortest possible string representation of the given long number that qualifies as an identifier in common programming languages (and HTML-id's :-) That is, it must start with a letter. 
char buf[] = new char[14];
int i = 0;
if (val < 0) {
    buf[i++] = '_';
    val = -(val + 1);
buf[i++] = ALPHAS[(int) (val % ALPHAS.length)];
val /= ALPHAS.length;
...
StringtoIdentityEncodedString(byte[] data)
to Identity Encoded String 
if (data == null) {
    return null;
char[] characters = new char[data.length];
for (int i = 0; i < characters.length; i++) {
    characters[i] = (char) (data[i] & 0xff);
return new String(characters);
...
IntegertoIdentityHashCodeInteger(Object value)
to Identity Hash Code Integer 
return new Integer(System.identityHashCode(value));
