public class CalendarAgent
extends ItinAgent
The CalendarAgent which uses the Sequence pattern extends the ItinAgent class. A calendar agent is created with a list of possible options for meeting times. This is encapsulated in the agent as an object called Briefcase}, which is a list of choices. The agent first visits all servers to check for conflicts for each of the choices. If at the end of the first round it finds at least one choice when none of the participants have a conflict, it revisits them again to insert an event in each participant's calendar database.
