Release 0.2 Copyright ©1994, 1995 by Todd Thomas All Rights Reserved. MiscUserGroup Inherits From: Object Declared In: <misckit/MiscUserGroup.h> Class Description This class is basically a wrapper around the notion of a UNIX system group. You can initialize a group either by groupId (gid) or by group name, then ask the object for the other. You can ask an instance to give you a List of all it's members, or ask the MiscUserGroup object for all the groups on your system. It is basically a very simple class that is supposed to fit well with the MiscFile and MiscUser classes. Since the underlying Unix functions used to retrieve the group information will climb the domain hierarchy, the information returned by either the class method +allGroups or the instance method -members is representative of all the information in all the domains (with duplicate entries removed). For instance, if your groups were setup like: Local domain: wheel - members = root, me other - members = me uucp - members = uucp Root domain: wheel - members = root, joe, fred other - members = joe, fred, ed, ted uucp - members = uucp games - members = <none> + allGroups would return : wheel, other, uucp, games. - members (for instance representing wheel) would return: root, me, joe, fred. Instance Variables int gid; char *groupname; gid The unique group id. groupname The character description of the group. Method Types + allGroups - initWithGroupId: - initWithGroupName: - free - groupId - groupName - members Class Methods allGroups + (List *)allGroups Returns a List containing MiscUserGroup objects representing all the groups on the system. If there are no groups on your system (highly unlikely I'd suspect) then nil is returned. You are responsible for freeing both the returned List and it's contents. This list will contain groups from all the domains from the local to root. Duplicate entries are removed. Instance Methods free - free Frees the groupname. groupId - (int)groupId Returns the unique gid that the receiver represents. See also: ± groupName groupName - (const char *)groupName Returns the group name that the receiver represents. See also: ± groupId initWithGroupId: - initWithGroupId:(int)groupId Initializes a MiscUserGroup class, given it's groupId. If there is no such groupId on the system, then the receiver is freed and nil is returned. This method is the designated initializer. See also: ± initWithGroupName: initWithGroupName: - initWithGroupName:(const char *)gname Initializes a MiscUserGroup class, given it's name. If there is no such group on the system, the receiver is freed and nil is returned. If gname is NULL, nil is returned. Example: MiscUserGroup *wheel = [ [MiscUserGroup alloc] initWithGroupName: "wheel"]; See also: ± initWithGroupId: members - (List *)members Returns a list of MiscUsers, representing all the members of the group the receiver represents. If the group has no members, nil will be returned. You are responsible for freeing both the returned List and it's contents. All the members in all the occurrences of the given group throughout the domain hierarchy will be merged together and returned. Duplicates are removed.
