  • Method Details

    • loadPlugins

      public List<IPluginDescriptor<?>> loadPlugins(String names) throws IOException
      Loads required plug-in's.

      Each plug-in must have a class called "name.server.Descriptor" that implement the interface com.iizix.IPluginDescriptor available.

      The plug-in definition should be found at the "name/schema/properties.xml", but the iiziGo modules have the "iizigo" module instead of "iizix". To figure out translation of names, a class called "name.server.Descriptor" is loaded and should implement the interface

      Parameters:
      names - The plug-in name, e.g. "com.iizigo.db,com.iizigo.term,com.iizigo.ws".
      Returns:
      The list of plug-in descriptors.
      Throws:
      IOException - If a plug-in failed to load.
