Member Function Documentation

void update () [virtual]
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.

Reimplemented from LazyObject.

void performCalculations () const [virtual]
This method must implement any calculations which must be (re)done in order to calculate the desired results.

Implements LazyObject.
