    6262== Party
    6363The party module contains basic interfaces for implementing your negotiation party.
    64 The main class is Party, which defines the basic functionality required for every negotiation party. The heart of the party is that your Party implements Connectable<Inform,Action>. Connectable contains 2 main functions: connect and disconnect.  When connect is called, your party receives a Connection over which it receives Inform objects and can send Action objects. What exactly is sent and received is determined by the protocol (see the protocol section below). For example if the SAOP protocol is used, your party will receive a YourTurn message, after which it decides on its action and sends it into the Connection. See also the example agent discussed below.

    6666The Inform objects are all available inside the inform package inside the party module.
     
    7474Parties, domains,  profiles and protocols are stored and used on remote machines.
    7575We use IRI's (internationalized resource identifier, which looks similar to the well known URLs you use in your web browser) to refer to them. These IRI's are packed inside objects like the PartyRef, ProtocolRef, ProfileRef, DomainRef so that it is clear what type of object the IRI is referring to.
    76 For example, when your party is initialized, it usually receives a Settings object that contains a ProfileRef. The intention is that the party fetches the actual profile from the web, using the IRI in the ProtocolRef. See the example agent below for an example.

    107107
    108 Example parties can be found [https://tracinsy.ewi.tudelft.nl/trac/Genius2/browser/exampleparties here]. An agent is compiled with maven. After compilation ({{{mvn package}}}) you get a {{{target/yourparty-X.Y.Z-jar-with-dependencies.jar}}} that can be copied into the parties server for deployment.

    157157== Preparing the jar file
    158 In order to put your agent on the [https://tracinsy.ewi.tudelft.nl/trac/Genius2PartiesServer partiesserver] for running, you need a jar file of your party.

    159159
    160160Normally the party includes all dependencies. The jar files are loaded with an isolated jar class loader that should avoid collisions with possibly identically named but possibly different packages in other jar files.
     
    163163Party jar files must have a Main-Class set in the MANIFEST.MF file. This main-class must implement Party and have a no-arg constructor.
    164164
    165 The example randomagent does this from the maven build script.

    166166
    167167We recommend to do initialization of the party only in the init() and not in the constructor or static code.

    171171= Writing a party in Python
    172 We provide a python-to-java adapter so that you can easily write your agent in python instead of Java. You can check the full working example code [https://tracinsy.ewi.tudelft.nl/trac/Genius2/browser/exampleparties/randompartypy/src/main/resources/RandomParty.py here]. A python-based agent looks like this:

    207207
    208 You need to wrap your python agent into a jar wrapper to get it accepted by the parties server. To do this, check the javadoc with the [https://tracinsy.ewi.tudelft.nl/trac/Genius2/browser/pythonadapter/src/main/java/genius2/pythonadapter/PythonPartyAdapter.java PythonPartyAdapter].
