clear.a

The clear.a action is the first version of the clear action in the Ultra blockchain. This action allows the creator of a group to remove all or a specified number of users from a group. The number of users removed is controlled by the nr_removals parameter.

Behavior

• The creator of the group can remove all or a specified number of users from the group.
• The nr_users field in the groups.a table will be decremented by the number of users removed.
• The action will fail if there are no users in the group.

Action Parameters

Name	C++ Type	JavaScript Type	Remarks
creator	name	String	The account that originally created the group.
group_id	uint64_t	Number/String	The ID used to identify the group to clear the users from.
nr_removals	optional<uint64_t>	Number/null	If not specified, all users will be removed. Otherwise, the number of users specified will be removed.

Note:
