Dear Atanu, The RightHandSide <https://www.dealii.org/developer/doxygen/deal.II/step_7.html#Equationdata> class in step-7 derives from the Function <https://www.dealii.org/developer/doxygen/deal.II/classFunction.html> class. This in turn defines the value_list <https://www.dealii.org/developer/doxygen/deal.II/classFunction.html#ab27693540ec0bb72ca53aca9d39f380e> function that, according to the documentation, calls the value <https://www.dealii.org/developer/doxygen/deal.II/classFunction.html#a9b79af0ecae7827b43058ab963ab8366> function. Since this function is marked as virtual, when the base class calls the value() function, the derived class' definition (i.e. what is defined in the RightHandSide class) is invoked.
I hope that this helps to explain what's going on here.
