Simulation parameter Annotation usage

The @SimParam annotation can be used to specify the simulation model parameters that will be received at runtime. The MiniReal system will pick up the list of simulation parameters and show them on the UI. The values inserted by the User on the UI will be fed to the simulation on runtime.

This annotation should be defined for arguments placed in the constructor of the Model class.

The @SimParam annotation takes one argument for its self, which is the default value for the parameter it is bound to. If no value is provided to the simulation model at runtime, this default value is used to initialize the model parameter.

• The key for this argument is named value and it takes a String object.
• Later on the String value is casted to the correct type with respect to the simulation parameter.

    // class constructor
    public Model(
        @SimParam(value = "500") int population,
        @SimParam(value = "100") int wealth
    ) {
        super(System.currentTimeMillis());
        this.population = population;
        createAgents(wealth);
    }

    // rest of code
}
