54 * PluginHostAdapter is a wrapper class that a Vamp host can use to
55 * make the C-language VampPluginDescriptor object appear as a C++
56 * Vamp::Plugin object.
57 *
58 * The Vamp API is defined in vamp/vamp.h as a C API. The C++ objects
59 * used for convenience by plugins and hosts actually communicate
60 * using the C low-level API, but the details of this communication
61 * are handled seamlessly by the Vamp SDK implementation provided the
62 * plugin and host use the proper C++ wrapper objects.
63 *
64 * See also PluginAdapter, the plugin-side wrapper that makes a C++
65 * plugin object available using the C query API.
