public bool set_for_id (string key_name, Value value)
Sets the first value associated with key_name in this.
This key_name is used to create a new ParamSpec instance, which is further used to create and
register a key using register_metadata_key. If key_name
already has a first value, old value is replaced by the new one.
A property key_name consists of segments consisting of ASCII letters and digits, separated by either the '-' or '_' character. The first character of a property key_name must be a letter. Key_names which violate these rules lead to undefined behaviour.
