RE: [Dsol-java] how to listen to fireEvent?

[Herman v. H. <h_v...@ho...>]

Hi,

I think I can provide you with the answer. the vehicle has to subscribe to 
the event. This is done with the addListener(ListenerInterface listener, 
EvenType event) method which is in the EventProducer class and thuss in your 
crane class. Assuming it is in you r constructor it should look like this:

public class Vehicle implements EventListenerInterface
{
	public Vehicle(Crane crane)
	{
		/** Call super class constructor*/
		super();

		/** Do all other stuff*/

		/** Add our listener*/
		try
		{
			Crane.addListener(this, CONTAINER_RELEASED_EVENT);
		}
		catch (Exception e)
		{
			e.printStackTrace();
		}
	}

	/** Methods*/

}

Hope this helps,

regards, Herman van Hovell
