Class AllPermission

java.lang.Object
java.security.Permission
java.security.AllPermission
All Implemented Interfaces:
Serializable, Guard
public final class AllPermission extends Permission
The AllPermission is a permission that implies all other permissions.

Note: Granting AllPermission should be done with extreme care, as it implies all other permissions. Thus, it grants code the ability to run with security disabled. Extreme caution should be taken before granting such a permission to code. This permission should be used only during testing, or in extremely rare cases where an application or applet is completely trusted and adding the necessary permissions to the policy is prohibitively cumbersome.
