Detailed Description

Class to generate unique ids, valid to be used in a DICOM environment.

the created UIDs have the following form: 'iso_root_uid'.'systemtype'.'mac of the system'.'software type'.'process id'.'timestamp+counter' the form of the first part of the UIDs were decided together with Sebastian Meyer several years ago.

the uids are unique even in a multi-threaded environment the mac of the system has to be unique of course

Member Function Documentation

static void DCMTree_Utils::UIDGenerator::initialize ( std::string  iso_root_uid,
std::string  systemtype,
std::string  softwaretype,
std::string  replacementMac = std::string() 
) [static]

function to be called exactly once before any other function is called this function sets some predefined values, especially the _prefix part of the UIDs up to the 'process id'

Parameters:
replacementMacoptional parameter. If a replacementMac is provided it will be used in the _prefix; otherwise the MAC adress is determined with the getMac() function. A replacementMac is especially useful if the getMac() cannot guarantee to return a unique MAC which could be the case if VMWare is installed (which installs its own virtual adapters)
static bool DCMTree_Utils::UIDGenerator::isInitialized ( ) [static]

return true if class is initialized

static std::string DCMTree_Utils::UIDGenerator::uid ( ) [static]

create a new uid
