Method

ByteBuffergetAsByteBuffer()
get As Byte Buffer 
try {

} catch (Exception e) {
    throw new RuntimeException(e.toString());
byte[]getAsBytes(List buffers)
Copies the contents of the buffers into a single byte[] 
int size = 0;
for (ByteBuffer buffer : buffers) {
    size += buffer.remaining();
byte[] arr = new byte[size];
int offset = 0;
for (ByteBuffer buffer : buffers) {
    int len = buffer.remaining();
...
StringgetAscii(ByteBuffer bytes)
get Ascii 
StringBuilder builder = new StringBuilder();
if (bytes.remaining() < 2)
    throw new IOException("too few bytes specified for string value!");
int numBytes = getUnsignedShort(bytes);
if (bytes.remaining() < numBytes)
    throw new IOException("too few bytes specified for string value!");
for (int i = 0; i < numBytes; i++)
    builder.append((char) bytes.get());
...
StringgetAsciiString(ByteBuffer buffer)
get Ascii String 
return getString(buffer, "US-ASCII");
int[]getAsIntArray(ByteBuffer yuv, int size)
get As Int Array 
byte[] b = new byte[size];
int[] result = new int[size];
yuv.get(b);
for (int i = 0; i < b.length; i++) {
    result[i] = b[i] & 0xff;

MapgetAttrs(Map fields)
get Attrs 
if (fields == null) {
    return new HashMap<String, byte[]>();
HashMap<String, byte[]> tempMap = new HashMap<String, byte[]>();

...
longgetBatch(ByteBuffer bb)
get Batch 
return bb.getLong(batchPos);
BigDecimalgetBigDecimalFromByteBuffer(ByteBuffer bytebuf, int start, int length, int scale)
get Big Decimal From Byte Buffer 
byte[] value = new byte[length];
bytebuf.get(value);
BigInteger unscaledValue = new BigInteger(value);
return new BigDecimal(unscaledValue, scale);
intgetBit(ByteBuffer in, int pos)
Get a bit from the input ByteBuffer Returns the bit at bit position pos in ByteBuffer in. 
return in.get(pos >> 3) & (1 << (pos % NBITS_PER_BYTE));
StringgetBitString(java.nio.ByteBuffer buffer, int lenBits)
get Bit String 
String s = "";
int len = (int) Math.ceil(lenBits / (double) Byte.SIZE);
if (null != buffer && buffer.remaining() >= len) {
    byte[] dest = new byte[len];
    buffer.get(dest, 0, len);
    char[] bits = new char[lenBits];
    for (int i = 0; i < lenBits; i++) {
        int mask = 0x1 << (Byte.SIZE - (i % Byte.SIZE) - 1);
