Class Itinerary

java.lang.Object
  |
  +--ajanta.pattern.Itinerary

All Implemented Interfaces:

java.io.Serializable

public class Itinerary

extends java.lang.Object

implements java.io.Serializable

Each agent contains an Itinerary which encapsulates the travel plan of the agent as a Sequence pattern. The basic unit of execution for an agent is the action it performs at each host. This is its computation, which is separate from its migration control. The exit protocol ( defined by its depart method of agent ), which is executed when the agent completes its computation task, requests the Itinerary to choose the next host and migrate to it.

void	insert(ajanta.pattern.Pattern p) It inserts a Pattern in Sequence Pattern of the Itinerary
void	join() It calls join method of Sequence Pattern
int	next(ajanta.server.AgentEnv host)
void	print() It prints the Itinerary by calling print method of Sequence Pattern
