Examples of org.jboss.util.id.UID

org.jboss.util.id.UID
A unique identifier (uniqueness only guarantied inside of the virtual machine in which it was created).
The identifier is composed of:
1. A long generated from the current system time (in milliseconds).
2. A long generated from a counter (which is the number of UID objects that have been created durring the life of the executing virtual machine).
```
 [ time ] - [ counter ] 
```
Numbers are converted to radix(Character.MAX_RADIX) when converting to strings.
This should provide adequate uniqueness for most purposes. @version $Revision: 2787 $ @author Jason Dillon
