- // summary:
- // This function generates random UUIDs, meaning "version 4" UUIDs.
- // description:
- // A typical generated value would be something like this:
- // "3b12f1df-5232-4804-897e-917bf397618a"
- //
- // For more information about random UUIDs, see sections 4.4 and
- // 4.5 of RFC 4122: http://tools.ietf.org/html/rfc4122#section-4.4
- //
- // This generator function is designed to be small and fast,
- // but not necessarily good.
- //
- // Small: This generator has a small footprint. Once comments are
- // stripped, it's only about 25 lines of code, and it doesn't
- // dojo.require() any other modules.
- //
- // Fast: This generator can generate lots of new UUIDs fairly quickly
- // (at least, more quickly than the other dojo UUID generators).
- //
- // Not necessarily good: We use Math.random() as our source
- // of randomness, which may or may not provide much randomness.
- // examples:
- // var string = dojox.uuid.generateRandomUuid();
- var HEX_RADIX = 16;
-
