This class allows to manage modules to be loaded, started and stopped within a PeerGroup. Modules that are loaded using the ModuleManager do not need to be listed within the PeerGroup advertisement, nor do they have to have published their ModuleSpec and ModuleImpl advertisements: the ModuleManager takes care of this task. However, other peers which may want to load the Module will also have to use its own loader (or the ModuleManager itself, of course): the ModuleManager only manages Modules on the local peer. The Module Manager allows, as an option, to use an application provided class loader. The default class loader is the PeerGroup class loader. The following exemple shows how to use the ModuleManager: <pre> // Get the peergroup PeerGroup group = getMyPeerGroup(); // Get the ModuleManager ModuleManager moduleManager = ModuleManager.getModuleManager (group); // Is the Module already loaded ? Module module = moduleManager.lookupModule ("SampleModule"); if (module == null) { // SampleModue is not loaded yet. Load it now. module = moduleManager.loadModule ( "SampleModule", "net.jxta.app.SampleModule.SampleModule"); } // Start SampleModule moduleManager.startModule ("SampleModule", moduleArgs);
