vlPlugin * vlTrader::getPlugin (  const std::string &  serviceGroup, const std::string &  service )

If multiple plugins are available, then the best match plugin will be returned. As of this writing, the best match algorithm is not implemented. Right now, you will simply get the first plugin (in the order it was loaded) that satisfies this request.

std::vector< vlPlugin * > vlTrader::getPluginsForGroup (  const std::string &  serviceGroup  )

The plugins are stored in std::vector. Definition at line 126 of file vltrader.cpp. References vlPluginManager::baseList(), loadPlugin(), vlPluginManager::loadPlugins(), and m_pluginMgr.
