- 方法详细资料
  - getGeneratedVersion
```
int getGeneratedVersion()
```
    Which variant, according to IETF RFC 4122, of UUID does this strategy generate? RFC 4122 defines 5 variants (though it only describes algorithms to generate 4):
    
    1 = time based
    
    2 = DCE based using POSIX UIDs
    
    3 = name based (md5 hash)
    
    4 = random numbers based
    
    5 = name based (sha-1 hash)
    
    Returning the values above should be reserved to those generators creating variants compliant with the corresponding RFC definition; others can feel free to return other values as they see fit.
    Informational only, and not used at this time.

    The supported generation version
  - generateUUID
```
UUID generateUUID(SharedSessionContractImplementor session)
```
    Generate the UUID.

    session - The session asking for the generation
    
    返回:
    
    The generated UUID.
