WpProperties

WpProperties is a data structure that contains string key-value pairs, which are used to send/receive/attach arbitrary properties to PipeWire objects.

This could be thought of as a hash table with strings as both keys and values. However, the reason that this class exists instead of using GHashTable directly is that in reality it wraps the PipeWire native struct spa_dict and struct pw_properties and therefore it can be easily passed to PipeWire function calls that require a struct spa_dict * or a struct pw_properties * as arguments. Or alternatively, it can easily wrap a struct spa_dict * or a struct pw_properties * that was given from the PipeWire API without necessarily doing an expensive copy operation.

WpProperties normally wraps a struct pw_properties, unless it was created with wp_properties_new_wrap_dict, in which case it wraps a struct spa_dict and it is immutable (you cannot add/remove/modify any key-value pair).

In most cases, it actually owns the struct pw_properties internally and manages its lifetime. The exception to that rule is when WpProperties is constructed with wp_properties_new_wrap, in which case the ownership of the struct pw_properties remains outside. This must be used with care, as the struct pw_properties may be free'ed externally.

WpProperties is reference-counted with wp_properties_ref and wp_properties_unref.
