Member Function Documentation

SequenceNumber * SequenceNumber::getInstance

(

)

[static]

Returns instance of the singleton

Returns:

instance of the singleton

Definition at line 18 of file SequenceNumber.cpp.

unsigned long SequenceNumber::getSequenceNumber

(

)

Returns system-wide unique IDs for any kind of objects which than can be distinguished. This method is protected with a mutex and thus only allows one thread at a time to enter it.

Returns:

unique ID.
