◆ initializeFrom()

void oofem::ConcreteFCM::initializeFrom ( InputRecord & ir)
overridevirtual

Initializes receiver according to object description stored in input record. This function is called immediately after creating object using constructor. Input record can be imagined as data record in component database belonging to receiver. Receiver may use value-name extracting functions to extract particular field from record. Note that initializeFrom may be called mutiple times.

Parameters
irInput record to initialize from.
priorityPriority of the input record. This is used to determine the order of initialization
