Method

intintFrombytes(byte[] b, int pos)
int Frombytes 
return b2i(b[pos]) + b2i(b[pos + 1]) * 256 + b2i(b[pos + 2]) * 65536 + b2i(b[pos + 3]) * 65536 * 256;
intintFromBytes(byte[] buffer)
int From Bytes 
return intFromBytes(buffer, 0, 4);
intintFromBytes(byte[] buffer, int offset)
Converts consecutive bytes from a buffer into an int. 
return (int) integralFromBytes(buffer, offset, 4);
intintFromBytes(byte[] bytes)
int From Bytes 
int x1 = bytes[0];
int x2 = bytes[1];
int x3 = bytes[2];
int x4 = bytes[3];
if (x1 < 0)
    x1 = x1 + 256;
if (x2 < 0)
    x2 = x2 + 256;
