n |= ((read(is) & 0xFFL) << 8);
n |= ((read(is) & 0xFFL) << 16);
n |= ((read(is) & 0xFFL) << 24);
n |= ((read(is) & 0xFFL) << 32);

longreadLong(InputStream stream)
read Long 
long result = 0;
for (int i = 0; i < BITS_IN_LONG; i += BITS_IN_BYTE)
    result |= ((long) readByte(stream)) << i;
return result;
longreadLong(InputStream stream)
read Long 
long a = readUInt(stream);
long b = readUInt(stream);
return a + (b << 32);
longreadLong(InputStream stream)
Reading long from stream 
long a = readUInt(stream);
long b = readUInt(stream);
return a + (b << 32);
intreadLong(InputStream stream)
read Long 
return readInt(stream);
longreadLongFrom(InputStream is)
This method allows to restore a long from the input stream. 
byte[] buf = readFully(8, is);
return ((buf[0] & 0xFFL) << 56) | ((buf[1] & 0xFFL) << 48) | ((buf[2] & 0xFFL) << 40)
        | ((buf[3] & 0xFFL) << 32) | ((buf[4] & 0xFFL) << 24) | ((buf[5] & 0xFFL) << 16)
        | ((buf[6] & 0xFFL) << 8) | (buf[7] & 0xFFL);
longreadLongLE(InputStream in)
read Long LE 
long ret = -1;
if (in != null) {
    ret = 0;
    for (int i = 0; i < 8; i++) {
        long i1 = in.read() & 0x0ff;
        ret += (i1 << (i * 8));
return ret;
longreadLongLE(InputStream in)
read little-endian long 
long b0 = in.read();
long b1 = in.read();
long b2 = in.read();
long b3 = in.read();
long b4 = in.read();
long b5 = in.read();
long b6 = in.read();
