Plugins

struct WpPlugin

WpPlugin is a base class for objects that provide functionality to the WirePlumber daemon.

Typically, a plugin is created within a module and then registered to make it available for use by the daemon. The daemon is responsible for calling wp_object_activate() on it after all modules have been loaded, the core is connected and the initial discovery of global objects is done.

Being a WpObject subclass, the plugin inherits WpObject’s activation system. For most implementations, there is only need for activating one feature, WP_PLUGIN_FEATURE_ENABLED, and this can be done by implementing only WpPluginClass::enable() and WpPluginClass::disable(). For more advanced plugins that need to have more features, you may implement directly the functions of WpObjectClass and ignore the ones of WpPluginClass.
