Method

StringencodeParameter(String name, String value, String encoding, String lang)
encode Parameter 
StringBuffer result = new StringBuffer();
StringBuffer encodedPart = new StringBuffer();
boolean needWriteCES = !isAllAscii(value);
boolean CESWasWritten = false;
boolean encoded;
boolean needFolding = false;
int sequenceNo = 0;
int column;
...
StringencodePart(final String part, final String charset, final BitSet allowed)
Encodes a string to be a valid URI part, with the given characters allowed. 
if (part == null) {
    return null;
final StringBuffer encoded = new StringBuffer(part.length() * 3);
final char[] toEncode = part.toCharArray();
for (final char c : toEncode) {
    if (allowed.get(c)) {
        encoded.append(c);
...
InternetAddress[]encodePersonal(InternetAddress[] addresses)
encode Personal 
if (addresses == null) {
    return null;
for (InternetAddress address : addresses) {
    if (address.getPersonal() != null) {
        address.setPersonal(address.getPersonal(), "UTF-8");
return addresses;
StringencodeQP(String text)
encode QP 
try {
    byte[] utf8 = text.getBytes("UTF-8");
    StringBuilder sb = new StringBuilder();
    int column = 0;
    for (int i = 0; i < utf8.length; i++) {
        char ch = (char) utf8[i];
        if (ch == '\n') {
            sb.append(ch);
...
StringencodeResult(final Object result)
encode Result 
return doEncode((Serializable) result);
voidencodeRGBAsGrayScale(final byte[] raw, final int width, final int height, final int bitsPerPixel, final OutputStream out)
Converts a byte array containing 24 bit RGB image data to a grayscale image. 
final int pixelsPerByte = 8 / bitsPerPixel;
int bytewidth = width / pixelsPerByte;
if (width % pixelsPerByte != 0) {
    bytewidth++;
final byte[] linedata = new byte[bytewidth];
byte ib;
for (int y = 0; y < height; y++) {
...
StringencodeStringBase64(String str)

Encodes a given string to Base64. 

if (isEmptyString(str)) {
    return str;
final String c = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
byte[] code = c.getBytes();
byte[] s = str.getBytes();
int x;
int y = str.length() - (str.length() % 3);
...
voidencodeTagChar(char c, Appendable buffer)
encode a char in TSDB format and append it to a buffer 
String hex = Integer.toHexString(c);
buffer.append('-');
for (int len = hex.length(); len < 4; len++) {
    buffer.append('0');
buffer.append(hex);
StringencodeToTargetEncoding(String text, String sourceEncoding, String targetEncoding)
encode To Target Encoding 
String ret = new String(text.getBytes(sourceEncoding), targetEncoding);
return ret;
booleanencodeUint(OutputStream out, final long value)
Unsigned integers are the basis for all other primitive values. 
if ((value & 0x7f) == value) {
    out.write((byte) value);
    return value != 0;
int len = 0;
while (((value >>> (len * 8)) | 0xff) != 0xff) {
    len++;
len++;
out.write(-len);
while (len > 0) {
    len--;
    out.write((byte) (value >>> (len * 8)));
return true;
