  +--projectinfosearch.AgentServer

All Implemented Interfaces:

AgentServerInt

public class AgentServer

extends java.lang.Object

implements AgentServerInt

An AgentServer must be "visible" and welcome agents to allow them to perform their mission

Constructor Summary

AgentServer(int serverPort)
Creates a DiscoveryServer to become visible on a given multicast group and a ServerSocket to receive agents.

Method Summary

void	agentMigrate(AgentObject agent, java.net.InetAddress dstAddress, int dstport) The agent wants to be sent to dstAddr and dstPort.
java.util.Vector	getFootprints() optional, not implemented
java.util.Vector	getResidingAgents() optional, not implemented
java.util.Vector	getServerNeighbors() This method creates a DiscoveryClient which will find the server's neighbors
static void	main(java.lang.String[] args) Reads the arguments from the command line (serverPort) and creates an AgentServer, quits if the procedure is wrong (wrong serverPort or nb of arguments).

Constructor Detail

AgentServer

public AgentServer(int serverPort)

Creates a DiscoveryServer to become visible on a given multicast group and a ServerSocket to receive agents. The TCP connections and the agent handling are performed by ReceivingThread.

Parameters:

serverPort - is the server port on which agents are expected

Method Detail

getServerNeighbors

public java.util.Vector getServerNeighbors()

This method creates a DiscoveryClient which will find the server's neighbors

Specified by:

getServerNeighbors in interface AgentServerInt

Returns:

a vector containing the neighbors

agentMigrate

public void agentMigrate(AgentObject agent,
                         java.net.InetAddress dstAddress,
                         int dstport)

The agent wants to be sent to dstAddr and dstPort. For this purpose a TCP connection is established. If the connection to another server is unsuccessful, the agent is sent home

Specified by:

agentMigrate in interface AgentServerInt

Parameters:

agent - is the AgentObject which wants to migrate

dstAddress - is the destination InetAddress

dstport - is the destination port

getFootprints

public java.util.Vector getFootprints()

optional, not implemented

Specified by:

getFootprints in interface AgentServerInt

getResidingAgents

public java.util.Vector getResidingAgents()

optional, not implemented

Specified by:

getResidingAgents in interface AgentServerInt

main

public static void main(java.lang.String[] args)

Reads the arguments from the command line (serverPort) and creates an AgentServer, quits if the procedure is wrong (wrong serverPort or nb of arguments).
