Member Function Documentation

virtual void ucc::Shared::Exclusive ( void  ) [virtual]

Convert object to an exclusive lock.

Many of our shared locking objects such as the "conditional lock" support the ability to switch between shared and exclusive locking modes. This derived protocol member allows one to temporarily assert exclusive locking when tied to such methods.

virtual void ucc::Shared::Share ( void  ) [virtual]

Share the lock with other referencers.

Many of our shared locking objects support the ability to switch between shared and exclusive mode. This derived protocol member allows one to restore the lock to shared mode after it has been made exclusive.
