set_for_id
Description:
Sets the 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 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.
Parameters:

the new value |
Returns:
