* Guid represents a UUID with "native" (little-endian) byte order |
| 24 |
* |
| 25 |
* From Wikipedia: |
| 26 |
* |
| 27 |
* > The first three fields are unsigned 32- and 16-bit integers and are subject |
| 28 |
* > to swapping, while the last two fields consist of uninterpreted bytes, not |
| 29 |
* > subject to swapping. This byte swapping applies even for versions 3, 4, and |
| 30 |
* > 5, where the canonical fields do not correspond to the content of the UUID. |
| 31 |
* |
| 32 |
* The first three fields of a GUID are encoded in little-endian byte order, |
| 33 |
* while the last three fields are in network (big-endian) byte order. This is |
| 34 |
* according to the history of the Microsoft definition of a GUID. |
| 35 |
* |
| 36 |
* According to the .NET Guid.ToByteArray method documentation: |
| 37 |
* |
| 38 |
* > Note that the order of bytes in the returned byte array is different from |
| 39 |
* > the string representation of a Guid value. The order of the beginning |
| 40 |
* > four-byte group and the next two two-byte groups is reversed, whereas the |
| 41 |
* > order of the last two-byte group and the closing six-byte group is the |
| 42 |
* > same. |
