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.
