[Opensim-dev] [libsl-dev] UUID format: dashed here to stay?

[John Hurliman]

It was actually a big performance boost by changing to the dashed format.
Internally, LLUUID is just a wrapper around the .NET Guid object which has a
ToString() method that produces a dashed UUID. The non-hyphenated version
removed the dashes which required an additional memory allocation on top of
searching through the string, and I decided to just drop it completely. If
you want to implement the same functionality in your client code it is just
mystring.Replace('-',''); but I would recommend switching over to the
hyphenated version that is here to stay.
