Method

voidwriteByteBuffer(ByteBuffer bbuf, String filename)
write Byte Buffer 
File file;
try {
    String logfile = "C:\\" + filename + ".txt";
    file = new File(logfile);
    boolean exists = file.exists();
    if (!exists) {
        try {
            file = new File(logfile);
...
intwriteByteBuffer(RandomAccessFile file, ByteBuffer buffer)
Write an entire ByteBuffer into a file.
return file.getChannel().write(buffer);
intwriteByteBuffer(WritableByteChannel channel, ByteBuffer buf, int bytesToWrite)
Writes bytes from buf to the channel until at least bytesToWrite number of bytes are written. 
int t = bytesToWrite; 
while (t > 0) {
    t -= channel.write(buf);
return bytesToWrite - t;
voidwriteBytesNoLength(ByteBuffer logBuf, byte[] b)
Write a byte array into the log. 
logBuf.put(b);
voidwriteByteString(ByteBuffer byteBuffer, String value)
write Byte String 
byteBuffer.putInt(value.length());
byteBuffer.put(value.getBytes());
voidwriteCDouble(ByteBuffer buffer, double value)
write C Double 
writeCLong(buffer, Double.doubleToLongBits(value));
voidwriteCharacterString(ByteBuffer buf, byte[] bytes)
Writes a character string into the buffer. 
if (bytes.length > 254) {
    throw new IllegalArgumentException(
            "The length of a character string must be between 0 and 254 octets.");
buf.put((byte) bytes.length);

voidwriteCInt(ByteBuffer buffer, int anInt)
write C Int 
if (anInt > -127 && anInt <= 127) {
    buffer.put((byte) anInt);
} else if (anInt >= Short.MIN_VALUE && anInt <= Short.MAX_VALUE) {
    buffer.put((byte) -128);
    buffer.putShort((short) anInt);
