Method

voidwriteString(String s, OutputStream out)
write String 
if (s == null) {
    writeInt(0, out);
    return;
int len = s.length();
writeInt(len, out);
for (int i = 0; i < len; i++)
    writChar(s.charAt(i), out);
...
voidwriteString(String str, ObjectOutputStream dos)
DOC zhao Comment method "writeString". 
if (str == null) {
    dos.writeInt(-1);
} else {
    byte[] byteArray = str.getBytes(UTF8);
    dos.writeInt(byteArray.length);
    dos.write(byteArray);
voidwriteString(String value, OutputStream os)
Writes a the provided string in a Hessian string representation to the provided output stream using UTF-8 encoding.
The string will be written with the following syntax: 
 S b16 b8 string-value
If the value is null, it will be written as 
 N 
if (value == null) {
    os.write('N');
} else {
    int length = value.length();
    int offset = 0;
    while (length > 0x8000) {
        int sublen = 0x8000;
        char tail = value.charAt(offset + sublen - 1);
...
voidwriteStringAsAsciiBytes(String in, OutputStream out)
Writes the given String string as ASCII bytes (0-127) to the given OutputStream output stream . 
final int length = in.length();
for (int i = 0; i < length; i++) {
    out.write(in.charAt(i));
voidwriteStringCompressed(ByteArrayOutputStream baos, String s)
write String Compressed 
try {
    writeCompressedData(baos, s.getBytes("UTF-8"));
} catch (UnsupportedEncodingException e) {
    throw new RuntimeException("Cannot write string", e);

        writeString(os, entry.getKey());
        writeString(os, entry.getValue());
} else {
    writeInt(os, 0);
