 * \struct WpFactory
 *
 * The WpFactory class allows accessing the properties and methods of
 * PipeWire Factory objects (`struct pw_factory`).
 *
 * A WpFactory is constructed internally by wireplumber, when the pipewire 
 * constructed factory objects are reported in by PipeWire registry 
 * and it is made available for wireplumber clients through the 
 * WpObjectManager API.
 *
 * \since 0.4.5
