SUUID is an extension of java.util.UUID class to be able to use a shorter version of the uuid inside urls

suuid.SUUID is just a class that provides a simple functionality: representing a uuid with less characters than it's standard form. Provided representation is in base 64 so it can be safely used in URLs.

For example the uuid:

70ccb163-e1c4-4079-8f9d-4d091bf51e75

can be represented as:

cMyxY-HEQHmPnU0JG_UedQ

which is 10 characters less than it's standard representation (I'm not counting the separators).

If this not satisfies your needs, I recommend you looking at this library: http://hashids.org/java/

How to use it

TODO: import maven dependency. By the moment copy&paste class or checkout the project and import.

• Create a SUUID from an existing UUID: new SUUID(uuid);
• Create a random SUUID: SUUID.randomSUUID()
• Create a SUUID from two longs (analog to UUID constructor): new SUUID(mostSignificantBits, leastSignificantBits)

To obtain the base64 representation you have to call suuid.toBase64(). The method toString() prints the same as it's corresponding UUID.

How suuid works

It's actually an extension of java.util.UUID class, but since this class is final the workaround is to wrap it and delegate.

It provides the same methods as UUID class.
