It is an implementation of L, and thus has all the methods that L provides, in addition to any methods documented below. =head1 SUBROUTINES =over =item C Note that in addition to what L normally does, this function also makes the new group be inherited by the C group. That is, the C group will automatically be a member of this group. =item C Description: ValidateGroupName checks to see if ANY of the users in the provided list of user objects can see the named group. Params: $name - String with the group name. @users - An array with Bugzilla::User objects. Returns: It returns the group id if successful and undef otherwise. =back =head1 METHODS =over =item C =over =item B Throws an error if the user cannot add or remove this group to/from a given bug, but doesn't specify if this is because the group doesn't exist, or the user is not allowed to edit this group restriction. =item B This method takes a single hashref as argument, with the following keys: =over =item C C The name of the group to add or remove. =item C C The ID of the bug to which the group change applies. =item C C The name of the product the bug belongs to. =item C C Must be either C or C, depending on whether the group must be added or removed from the bug. Any other value will generate an error. =back =item C A C object on success, else an error is thrown. =back =item C Throws an error if this group is not visible (according to visibility groups) to the currently-logged-in user. =item C =over =item B Determines whether it's OK to remove this group from the database, and throws an error if it's not OK. =item B =over =item C C If you want to only check if the group can be deleted I, under any circumstances, specify C to just do the most basic tests (the other parameters will be ignored in this situation, as those tests won't be run). =item C C True if it would be OK to remove all users who are in this group from this group. =item C C True if it would be OK to remove all bugs that are in this group from this group. =item C C True if it would be OK to stop all flagtypes that reference this group from referencing this group (e.g., as their grantgroup or requestgroup). =item C C True if it would be OK to remove this group from all group controls on products. =back =item B (nothing) =back =item C Returns an arrayref of L objects representing people who are "directly" in this group, meaning that they're in it because they match the group regular expression, or they have been actually added to the group manually. =item C Accepts a list of groups and returns a list of all the groups whose members inherit membership in any group on the list. So, we can determine if a user is in any of the groups input to flatten_group_membership by querying the user_group_map for any user with DIRECT or REGEXP membership IN() the list of groups returned. =back
