Member Function Documentation

◆ performCalculations()

void performCalculations ( ) const

overridevirtual

This method must implement any calculations which must be (re)done in order to calculate the desired results.

Implements LazyObject.

Definition at line 102 of file noarbsabrinterpolatedsmilesection.cpp.

Here is the call graph for this function:

◆ update()

void update ( )

overridevirtual

This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.

Implements Observer.
