Constructor & Destructor Documentation

◆ ~Simulator()

virtual Simulator::~Simulator ( )
virtualdefault

Acts as constructor, returns the instance of singleton object

Member Function Documentation

◆ advanceEpoch()

void Simulator::advanceEpoch ( int currentEpoch) const

void Simulator::finish ( )

Setup simulation.

Begin terminating the simulator.

Definition at line 70 of file Simulator.cpp.

◆ getConfigFileName()

string Simulator::getConfigFileName ( ) const

Seed used to initialize parameters.

Definition at line 333 of file Simulator.cpp.
