Agent - interface projectinfosearch.Agent.

Interface which must be implemented by AgentObject s

agentArrived(AgentServer, InetAddress, int) - Method in class projectinfosearch.AgentObject

When an AgentObject arrives at a server, this method is invoqued.

agentArrived(AgentServer, InetAddress, int) - Method in interface projectinfosearch.Agent

An agent server invokes this method.

AgentClient - class projectinfosearch.AgentClient.

An AgentClient is an application which finds servers, creates and sends an AgentObject and displays its results when it returns

AgentClient(int) - Constructor for class projectinfosearch.AgentClient

creates a DiscoveryClient, displays the running servers which were found, creates an AgentSender, displays the results of the AgentObject's "journey"

agentMigrate(AgentObject, InetAddress, int) - Method in class projectinfosearch.AgentServer

The agent wants to be sent to dstAddr and dstPort.

agentMigrate(AgentObject, InetAddress, int) - Method in interface projectinfosearch.AgentServerInt

AgentServerInt - interface projectinfosearch.AgentServerInt.

must be implemented by an AgentServer

D

DiscoveryClient - class projectinfosearch.DiscoveryClient.

A discovery client is able to find AgentServers

DiscoveryClient(InetAddress, int) - Constructor for class projectinfosearch.DiscoveryClient

getVisitedServers() - Method in class projectinfosearch.AgentObject

returns the vector containing the visited AgentServers

M

main(String[]) - Static method in class projectinfosearch.AgentClient

Reads the arguments from the command line (homePort) and creates an AgentClient

main(String[]) - Static method in class projectinfosearch.AgentServer

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

P

printDiscoveryResult(Vector) - Method in class projectinfosearch.AgentClient

prints the connected running servers

projectinfosearch - package projectinfosearch

Q

queryResult(int) - Method in class projectinfosearch.AgentSender
