Details

gmCreateClass allows the suer to add a new variable/class to the database. If set is given a type, the new class will be inferred from parent, which is gmObject by default.

gmAddMembers allows to add classes/variable to other classes. The option required determines, if this member must be initialised during construction of an instance of class.

gmCreateRightsGroup and gmCreateUserGroup create new rights or user groups. A rights group contains the sets readers and writers, consisting of usergroups, which determine, who is allowed to access or change an object. The rights group of an object can be set with gmSetRights after the initialisation of the object.

gmCreateUser is for creation of a new user. You may add this new user to the appropriate usergroups using gmAddUserToGroup.

During object initialisation using gmAdd the arguments rg can give the needed rights group. If is not given, a default value is used. This can be set by gmDefaultRightsGroup.
