Class SecurityContext.Permission<T>

java.lang.Object

javolution.context.SecurityContext.Permission<T>

Enclosing class:

SecurityContext

public static class SecurityContext.Permission<T>
extends Object

A permission associated to a specific class/action/instance. There are three levels of permission possible, at the class/category level, at the action level and at the instance level. Any permission granted/revoked at the higher level is explicitly granted/revoked at the lower level. The order in which the permission are granted/revoked is important. For example, it is possible to grant a permission at the class level, then to revoke it at the action or instance level. In which case, for that class the permission is granted for all actions/instances except for those actions/instances for which the permission has been explicitly revoked.
