Method

voidlongToBytes(long x, byte[] dest, int offset)
long To Bytes 
bufferLock.lock();
try {
    longbuffer.clear();
    longbuffer.putLong(0, x);
    System.arraycopy(longbuffer.array(), 0, dest, offset, Long.BYTES);
} finally {
    bufferLock.unlock();
byte[]longToBytesNoLeadZeroes(long val)
Converts a long value into a byte array. 
byte[] data = ByteBuffer.allocate(8).putLong(val).array();
return stripLeadingZeroes(data);
byte[]longToFourBytesFlip(long l)
long To Four Bytes Flip 
ByteBuffer buffer = ByteBuffer.allocate(Byte.BYTES * 8);
buffer.putLong(l);
return Arrays.copyOfRange(buffer.array(), 4, 8);
intlongToHeight(long x)
long To Height 
ByteBuffer buffer = ByteBuffer.allocate(8);
buffer.order(ByteOrder.LITTLE_ENDIAN);
buffer.putLong(0, x);
return buffer.getInt(4);
StringlongToIPv4(Long ip)
long To I Pv 
ByteBuffer buffer = ByteBuffer.allocate(Integer.SIZE / 8);
buffer.putInt(ip.intValue());
try {
    InetAddress addr = InetAddress.getByAddress(buffer.array());
    return addr.getHostAddress();
} catch (UnknownHostException e) {
    return null;
byte[]longToLE(long lVal)
Pack integer value to Little Endian. 
ByteBuffer bb = ByteBuffer.allocate(Integer.SIZE / 8);
bb.order(ByteOrder.LITTLE_ENDIAN);
bb.putLong(lVal);
return bb.array();
short[]longToShorts2(long value)
long To Shorts 
short[] shorts = new short[4];
ByteBuffer b = ByteBuffer.allocate(8);
b.putLong(value);
b.rewind();
shorts[0] = b.getShort();
shorts[1] = b.getShort();
shorts[2] = b.getShort();
shorts[3] = b.getShort();
...
byte[]shortToByteArray(short inShort)
short To Byte Array 
byte[] bArray = new byte[2];
ByteBuffer bBuffer = ByteBuffer.wrap(bArray);
ShortBuffer lBuffer = bBuffer.asShortBuffer();
lBuffer.put(inShort);
return bArray;
byte[]shortToBytes(short s)
short To Bytes 
ByteBuffer b = ByteBuffer.allocate(2);
b.putShort(s);
return b.array();
String[]stringsFromBinary(final byte[] binary)
Utility to convert bytes to a String 
final ByteBuffer buf = ByteBuffer.wrap(binary);
final int count = buf.getInt();
final String[] result = new String[count];
for (int i = 0; i < count; i++) {
    final int size = buf.getInt();
    final byte[] strBytes = new byte[size];
    buf.get(strBytes);
    result[i] = new String(strBytes, GEOWAVE_CHAR_SET);
