Class GroupRoleManager

java.lang.Object

org.casbin.jcasbin.rbac.DefaultRoleManager

org.casbin.jcasbin.rbac.GroupRoleManager

All Implemented Interfaces:

RoleManager

public class GroupRoleManager
extends DefaultRoleManager

GroupRoleManager is used for authorization if the user's group is the role who has permission, but the group information is in the default format (policy start with "g") and the role information is in named format (policy start with "g2", "g3", ...). e.g. p, admin, domain1, data1, read g, alice, group1 g2, group1, admin, domain1 As for the previous example, alice should have the permission to read data1, but if we use the DefaultRoleManager, it will return false. GroupRoleManager is to handle this situation.
