The “client” package

The package manages actions of clients in evacuation simulation as updates the state of an agent or environment object. In the package, we create a class named “EvacuationSimAdapter” as an adapter to connect, control clients.

To implement the “EvacuationSimAdapter” class:

• Create a new class inside the “client” package and name it “EvacuationSimAdapter”.
• Copy the code given below that describes the full implementation of a “EvacuationSimAdapter” class.

import edu.utdallas.mavs.divas.core.sim.common.state.VirtualState;
import edu.utdallas.mavs.evacuation.simulation.sim.common.state.ActivatedObjectState;

public class EvacuationSimAdapter extends SimAdapter
{

    @Inject
    public EvacuationSimAdapter(SimFacade simFacade)
    {
        super(simFacade);
    }

    @Override

        }
        simFacade.createEnvObject(envObject);
    }
