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.
