| Methods Summary |
|---|
| public static int | bytesToInt(byte[] array, int offset)Unmarshal a byte array to an integer.
Assume the bytes are in BIGENDIAN order.
i.e. array[offset] is the most-significant-byte
and array[offset+3] is the least-significant-byte.
int b1, b2, b3, b4;
b1 = (array[offset++] << 24) & 0xFF000000;
b2 = (array[offset++] << 16) & 0x00FF0000;
b3 = (array[offset++] << 8) & 0x0000FF00;
b4 = (array[offset++] << 0) & 0x000000FF;
return (b1 | b2 | b3 | b4);
|
| public static long | bytesToLong(byte[] array, int offset)Unmarshal a byte array to an long.
Assume the bytes are in BIGENDIAN order.
i.e. array[offset] is the most-significant-byte
and array[offset+7] is the least-significant-byte.
long l1, l2;
l1 = (long)bytesToInt(array, offset) << 32;
l2 = (long)bytesToInt(array, offset+4) & 0xFFFFFFFFL;
return (l1 | l2);
