Apéndice C: Métodos de SecurityManager

Esta tabla lista los permisos chequeados mediante las implementaciones de los métodos de java.lang.SecurityManager. Cada método de chequeo llama al método SecurityManager.checkPermission con el permiso indicado, excepto para los permisos checkConnect y checkRead que toman un argumento de contexto. Los métodos checkConnect y checkRead esperan que el contexto sea un AccessControlContext y llaman al método checkPermission del permiso con el permiso especificado.
