Method

intgetSize(int size, ByteBuffer buffer)
get Size 
switch (size) {
case 0:
    return 1;
case 1:
    return 2;
case 2:
    return 4;
case 3:
...
intgetSizePrefix(ByteBuffer bb)
Extract the size prefix from a `ByteBuffer`. 
return bb.getInt(bb.position());
intgetSmallSmartInt(ByteBuffer buffer)
Gets a small smart integer from the buffer. 
if ((buffer.get(buffer.position()) & 0xff) < 128) {
    return (buffer.get() & 0xff) - 1;
int shortValue = buffer.getShort() & 0xFFFF;
return shortValue - 32769;
intgetSmart(ByteBuffer buf)
get Smart 
int peek = buf.get(buf.position()) & 0xFF;
if (peek < 128) {
    return buf.get() & 0xFF;
} else {
    return (buf.getShort() & 0xFFFF) - 32768;
intgetSmartOld(ByteBuffer in)
get Smart Old 
int value = in.get() & 0xff;
if (value < 128)
    return value;
value = value << 8;
value += (in.get() & 0xff);
return value - 32768;
intgetSurrogateKey(byte[] data, ByteBuffer buffer)
Below method will be used to get the surrogate key 
int lenght = 4 - data.length;
for (int i = 0; i < lenght; i++) {
    buffer.put((byte) 0);
buffer.put(data);
buffer.rewind();
int surrogate = buffer.getInt();
buffer.clear();
...
longgetTableUuid(ByteBuffer rowKey)
get Table Uuid 
return rowKey.getLong(rowKey.position() + 1);
ByteBuffergetTempByteBuffer()
get Temp Byte Buffer 
synchronized (_cacheByteBuffer) {
    if (!_cacheByteBufferInUse) {
        _cacheByteBufferInUse = true;
        return _cacheByteBuffer;
return ByteBuffer.allocate(BUFFER_LEN);
byte[]getTerminatedArray(ByteBuffer buf)
get Terminated Array 
int start = buf.position();
while (buf.get() != 0) {
int end = buf.position();
byte[] bytes = new byte[end - start - 1]; 
buf.position(start);
buf.get(bytes);
buf.position(end); 
...
intgetTriByte(ByteBuffer buf)
Reads a 'tri-byte' from the specified buffer. 
return ((buf.get() & 0xFF) << 16) | ((buf.get() & 0xFF) << 8) | (buf.get() & 0xFF);
