createAddress()

StatusCode CalibXmlCnvSvc::createAddress ( unsigned char svc_type, const CLID & clid, const std::string * par, const unsigned long * ip, IOpaqueAddress *& refpAddress )

virtual

Create an XML address using explicit arguments to identify a single object

Parameters

svc_type	the service type
CLID	the CLID of the XML Element for which an address is created
par	an array of three strings containing the format version, calibration type name and the flavor, in this order
ip	has a single element, the serial number of the MySQL row which corresponds to this element
refpAddress	the new address created

Returns

a StatusCode giving the status of the address creation
