Private Attributes | |
| UUID_Time | time_last_ |
| The system time when that last uuid was generated. | |
| UUID_State | uuid_state_ |
| The UUID generator persistent state. | |
| ACE_SYNCH_MUTEX * | lock_ |
| bool | destroy_lock_ |
| bool | is_init_ |
| Initalization state of the generator. | |
Type to represent UTC as a count of 100 nanosecond intervals since 00:00:00.00, 15 October 1582.
| ACE_Utils::UUID_Generator::UUID_Generator | ( | void | ) |
Default constructor.
| ACE_Utils::UUID_Generator::~UUID_Generator | ( | ) |
Destructor.
| void ACE_Utils::UUID_Generator::generate_UUID | ( | 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
| UUID* ACE_Utils::UUID_Generator::generate_UUID | ( | 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::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::get_timestamp_and_clocksequence | ( | UUID_Time & | timestamp, | |
| ACE_UINT16 & | clockSequence | |||
| ) | [private] |
Obtain a UUID timestamp and clock sequence. Compensate for the fact that the time obtained from getSystem time has a resolution less than 100ns.
| void ACE_Utils::UUID_Generator::init | ( | void | ) |
Initialize the UUID generator
| 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.
| void ACE_Utils::UUID_Generator::lock | ( | ACE_SYNCH_MUTEX * | lock, | |
| bool | release_lock | |||
| ) |
Set a new locking strategy and return the old one.
bool ACE_Utils::UUID_Generator::destroy_lock_ [private] |
bool ACE_Utils::UUID_Generator::is_init_ [private] |
Initalization state of the generator.
ACE_SYNCH_MUTEX* ACE_Utils::UUID_Generator::lock_ [private] |
The system time when that last uuid was generated.
The UUID generator persistent state.
