Method

StringconvertBufferToString(ByteBuffer buffer)
convert Buffer To String 
if (buffer.remaining() == 0)
    return "";
byte[] bytes = new byte[buffer.limit()];
buffer.get(bytes);
return new String(bytes);
StringdecodeString(ByteBuffer bb)
decode String 
return Charset.forName("UTF-8").decode(bb).toString();
StringdecodeString(ByteBuffer buffer, String charset)
Convert the bytes in a given buffer to a string, using a given charset. 
if (buffer == null) {
    return null;
if (charset == null) {
    throw new IllegalArgumentException("charset");
try {
    return new String(buffer.array(), buffer.position(), buffer.limit() - buffer.position(), charset);
...
StringdecodeString(ByteBuffer src)
decode String 
CharsetDecoder theDecoder = decoder.get();
theDecoder.reset();
final CharBuffer dst = CharBuffer.allocate((int) ((double) src.remaining() * theDecoder.maxCharsPerByte()));
CoderResult cr = theDecoder.decode(src, dst, true);
if (!cr.isUnderflow())
    cr.throwException();
cr = theDecoder.flush(dst);
if (!cr.isUnderflow())
...
StringgetStr(ByteBuffer buff)
read a String from a ByteBuffer that was written w/the putStr method 
short len = buff.getShort();
if (len == 0) {
    return null;
} else {
    byte[] b = new byte[len];
    buff.get(b);
    return new String(b);
StringgetString(@Nonnull final ByteBuffer src)
get String 
final int size = src.getInt();
if (size == -1) {
    return null;
final char[] array = new char[size];
for (int i = 0; i < size; i++) {
    array[i] = src.getChar();
return new String(array);
StringgetString(ByteBuffer bb)
Inputs a string from a ByteBuffer. 
int size = bb.getShort();
char[] charBuffer = new char[size];
for (int i = 0; i < size; i++) {
    charBuffer[i] = bb.getChar();
return new String(charBuffer, 0, size);
StringgetString(ByteBuffer buf)
Gets an RS2 string from the buffer. 
StringBuilder bldr = new StringBuilder();
char c;
while ((c = (char) buf.get()) != 10) {
    bldr.append(c);
return bldr.toString();
StringgetString(ByteBuffer buf)
get String 
int len = buf.getShort(); 
if (len == -1)
    return null;
char[] cs = new char[len];
for (int i = 0; i < len; i++) {
    cs[i] = buf.getChar();
return new String(cs);
...
StringgetString(ByteBuffer buf)
get String 
StringBuilder bldr = new StringBuilder();
int b;
while ((b = (buf.get() & 0xFF)) != 0) {
    bldr.append((char) b);
return bldr.toString();
