| 35 | * This is an interface to the Action object, used in decision-making. It can | |
| 36 | * tell the name of the action, and is able to return the part of the | |
| 37 | * Contextual ADI, related to the action itself (for example, the parameters to | |
| 38 | * the Action, or arguments to the methods to be invoked). | |
| 39 | * | |
| 40 | * <p>According to ISO 10181-3 authorisation framework, Contextual ADI is the | |
| 41 | * Access Decision Information that depends on the requested action and other | |
| 42 | * circumstances. This interface allows the retrieval of the access decision | |
| 43 | * information that directly depends on the action to be performed. Note that | |
| 44 | * the action name itself could be viewed as a part of the ADI. | |
| 45 | * | |
| 46 | * <p>For example, if an Action is a method, the Contextual ADI could be a | |
| 47 | * collection of arguments to the method call. However, neither the action is | |
| 48 | * restricted to be a method, nor the format of the ADI is specified. It is up | |
| 49 | * to the implementors of the Action and AccessPolicy objects. As long as the | |
| 50 | * format is agreed between them, the system will work properly. | |
