Method

intreadVarint(ByteBuffer buffer)
Read an integer stored in variable-length format using zig-zag decoding from Google Protocol Buffers. 
int value = 0;
int i = 0;
int b;
while (((b = buffer.get()) & 0x80) != 0) {
    value |= (b & 0x7f) << i;
    i += 7;
    if (i > 28)
        throw illegalVarintException(value);
...
intreadVarInt(ByteBuffer buffer)
read Var Int 
int i = 0;
int j = 0;
while (true) {
    int b0 = buffer.get();
    i |= (b0 & 127) << j++ * 7;
    if (j > 5) {
        throw new IOException("VarInt too big");
    if ((b0 & 128) != 128) {
        break;
return i;
intreadVarInt(ByteBuffer stream)
read Var Int 
final byte b[] = new byte[1];
int count = 0;
int result = 0;
do {
    if (count == 5) {
        throw new IOException("stream corrupted");
    stream.get(b);
...
intreadVarIntRest(ByteBuffer buff, int b)
read Var Int Rest 
int x = b & 0x7f;
b = buff.get();
if (b >= 0) {
    return x | (b << 7);
x |= (b & 0x7f) << 7;
b = buff.get();
if (b >= 0) {
...
inttoInt(ByteBuffer buffer)
to Int 
return toByteBuffer(buffer, Integer.BYTES).getInt();
inttoInt(ByteBuffer buffer)
Convert buffer to an integer. 
return toInt(buffer, buffer.position(), buffer.remaining());
inttoInt(ByteBuffer bytes)
Convert a byte buffer to an integer. 
return bytes.getInt(bytes.position());
inttoInt(ByteBuffer value)
to Int 
int result = 0;
try {
    if (value != null) {
        int originPos = value.position();
        result = value.getInt();
        value.position(originPos);
} catch (Exception ex) {
...
inttoInt16BE(ByteBuffer buf, int[] out)
to Int BE 
int samples = 0;
while (buf.remaining() >= 2 && samples < out.length) {
    out[samples++] = (short) (((buf.get() & 0xff) << 8) | (buf.get() & 0xff));
return samples;
