Member Function Documentation

UUID * ACE_Utils::UUID_Generator::generateUUID (  ACE_UINT16    version = 0x0001, u_char    variant = 0x80 )

Format timestamp, clockseq, and nodeID into a VI UUID. For generating UUID's with thread and process ids use variant=0xc0

void ACE_Utils::UUID_Generator::generateUUID (  UUID &   , ACE_UINT16    version = 0x0001, u_char    variant = 0x80 )

Format timestamp, clockseq, and nodeID into an UUID of the specified version and variant. For generating UUID's with thread and process ids use variant=0xc0

void ACE_Utils::UUID_Generator::get_systemtime (  UUID_time &    timeNow )  [private]

Obtain the system time in UTC as a count of 100 nanosecond intervals since 00:00:00.00, 15 October 1582 (the date of Gregorian reform to the Christian calendar).

void ACE_Utils::UUID_Generator::get_timestamp (  UUID_time &    timestamp )  [private]

Obtain a UUID timestamp. Compensate for the fact that the time obtained from getSystem time has a resolution less than 100ns.

void ACE_Utils::UUID_Generator::init (  void    )

ACE_SYNCH_MUTEX * ACE_Utils::UUID_Generator::lock (  ACE_SYNCH_MUTEX *    lock, int    release_lock )

Set a new locking strategy and return the old one.

ACE_SYNCH_MUTEX * ACE_Utils::UUID_Generator::lock (  void    )

The locking strategy prevents multiple generators from accessing the UUID_state at the same time. Get the locking strategy.
