37 | * This action doPerforms an Access Control List and places it into | |
38 | * the RunData object, so it is easily available to modules. The ACL | |
39 | * is also placed into the session. Modules can null out the ACL to | |
40 | * force it to be rebuilt based on more information. | |
41 | * | |
42 | * <p> | |
43 | * | |
44 | * Turbine uses a User-Role-Permission arrangement for access control. | |
45 | * Users are assigned Roles. Roles are assigned Permissions. Turbine | |
46 | * modules then check the Permission required for an action or | |
47 | * information with the set of Permissions currently associated with | |
48 | * the session (which are dependent on the user associated with the | |
49 | * session.) | |
50 | * | |
51 | * <p> | |
52 | * | |
53 | * The criteria for assigning Roles/Permissions is application | |
54 | * dependent, in some cases an application may change a User's Roles | |
55 | * during the session. To achieve flexibility, the ACL takes an | |
56 | * Object parameter, which the application can use to doPerform the | |
57 | * ACL. | |
58 | * | |
59 | * <p> | |
60 | * | |
61 | * This action is special in that it should only be executed by the | |
62 | * Turbine servlet. | |
