StringconvertStringToLiteral(String className, String value)
convert String To Literal 
if (value == null) {
    return null;
} else if ("String".equals(className)) {
    return "\"" + value.replaceAll("\'", "\\'") + "\"";
} else if ("Number".equals(className)) {
    if (value.indexOf(".") == -1) {
        return "Integer.valueOf(" + value + ")";
    } else {
...
ObjectconvertStringToObject(String value, Class type)
Not support negative numeric value: - http://en.wikipedia.org/wiki/Double-precision_floating-point_format 
Object obj = null;
try {
    if (String.class.equals(type)) {
        obj = value;
    if (Long.class.equals(type) || long.class.equals(type)) {
        obj = Long.parseLong(value);
    } else if (Integer.class.equals(type) || int.class.equals(type)) {
...
byte[]convertStringToPrimaryKey(String keyString)

Converts a String to the 192-bit primary key.

Converts the given key to lower case prior to conversion to binary. 
if ((keyString != null) && (!"".equals(keyString))) {
    keyString = keyString.toLowerCase();
    byte[] bArray = new byte[(keyString.length() / 2)];
    for (int i = 0; i < bArray.length; i++) {
        bArray[i] = (byte) Integer.parseInt(keyString.substring(i * 2, i * 2 + 2), 16);
    return bArray;
return null;
ObjectconvertStringToPrimitive(Object object, Class toType)
convert String To Primitive 
if (toType == boolean.class || toType == Boolean.class) {
    return Boolean.valueOf((String) object);
if (toType == char.class || toType == Character.class) {
    return new Character(((String) object).charAt(0));
if (toType == byte.class || toType == Byte.class) {
    return new Byte((String) object);
...
ObjectconvertStringToPrimitive(String value, Class destinationClass)
convert String To Primitive 
if ((destinationClass == int.class || destinationClass == Integer.class)) {
    return new Integer(value);
if ((destinationClass == boolean.class || destinationClass == Boolean.class)) {
    return Boolean.valueOf(value);
if ((destinationClass == short.class || destinationClass == Short.class)) {
    return new Short(value);
...
StringconvertStringToSafeFilename(String s)
convert String To Safe Filename 
String ret = s.toLowerCase();
ret = ret.replaceAll("[\\\\\\/\\:\\*\\?\\\"\\<\\>\\|\\s\\,]", "-");
return ret;
ObjectconvertStringToValue(String txt, Class klass)
convert String To Value 
Object v = null;
try {
    if (klass.equals(Double.class) || klass.equals(Double.TYPE))
        v = Double.parseDouble(txt);
    else if (klass.equals(Float.class) || klass.equals(Float.TYPE))
        v = Float.parseFloat(txt);
    else if (klass.equals(Integer.class) || klass.equals(Integer.TYPE))
        v = Integer.parseInt(txt);
...
StringconvertStringToVarName(final String str)
convert String To Var Name 
return str.toUpperCase().replaceAll("[:punct:\\(\\)\\]\\['-]", "").replaceAll(" +", "_");
byte[]convertStringToWord(String strValue)
Converts a given string into a word of bytes 
byte[] word = new byte[2];
try {
    byte intRegVal = 0;
    for (int i = strValue.length(); i > 0; i--) {
        intRegVal = (byte) (intRegVal
                + Math.pow(16, strValue.length() - i) * Byte.parseByte(strValue.substring(i - 1, i), 16));
    word[0] = (byte) (intRegVal >>> 8 & 0xFF);
...
StringconvertStringWithReplacementPattern(final String originalString, final String pattern, final String replace)
This method returns a string with characters replaced. 
if (originalString != null) {
    final int len = pattern.length();
    final StringBuffer sb = new StringBuffer();
    int found = -1;
    int start = 0;
    while ((found = originalString.indexOf(pattern, start)) != -1) {
        sb.append(originalString.substring(start, found));
        sb.append(replace);
