| 40 | * The BasicPermission class extends the Permission class, and | ||
| 41 | * can be used as the base class for permissions that want to | ||
| 42 | * follow the same naming convention as BasicPermission. | ||
| 43 | * <P> | ||
| 44 | * The name for a BasicPermission is the name of the given permission | ||
| 45 | * (for example, "exit", | ||
| 46 | * "setFactory", "print.queueJob", etc). The naming | ||
| 47 | * convention follows the hierarchical property naming convention. | ||
| 48 | * An asterisk may appear by itself, or if immediately preceded by a "." | ||
| 49 | * may appear at the end of the name, to signify a wildcard match. | ||
| 50 | * For example, "*" and "java.*" are valid, while "*java", "a*b", | ||
| 51 | * and "java*" are not valid. | ||
| 52 | * <P> | ||
| 53 | * The action string (inherited from Permission) is unused. | ||
| 54 | * Thus, BasicPermission is commonly used as the base class for | ||
| 55 | * "named" permissions | ||
| 56 | * (ones that contain a name but no actions list; you either have the | ||
| 57 | * named permission or you don't.) | ||
| 58 | * Subclasses may implement actions on top of BasicPermission, | ||
| 59 | * if desired. | ||
