LIFECYCLE_ACTION
Allows the lifecycle management of the target applications.- See Also:
-

andpid
. The pattern specified in thesigner
is matched with the Distinguished Name chain used to sign the application. Wildcards in a DN are not matched according to the filter string rules, but according to the rules defined for a DN chain. The attributepid
is matched with the PID of the application according to the filter string rules.If the
filter
isnull
then it matches"*"
. Ifactions
is"*"
then it identifies all the possible actions.- Parameters:
filter
- filter to identify application. The valuenull
is equivalent to"*"
and it indicates "all application".actions
- comma-separated list of the desired actions granted on the applications or "*" means all the actions. It must not benull
. The order of the actions in the list is not significant.- Throws:
InvalidSyntaxException

Method Details
-
setCurrentApplicationId
This method can be used in theProtectionDomain
implementation in theimplies
method to insert the application ID of the current application into the permission being checked. This enables the evaluation of the<<SELF>>
pseudo targets.- Parameters:
applicationId
- the ID of the current application.- Returns:
- the permission updated with the ID of the current application
-
implies
Checks if the specifiedpermission
is implied by this permission. The method returns true under the following conditions:- This permission was created by specifying a filter (see
ApplicationAdminPermission(String, String)

otherPermission
was created for a particularApplicationDescriptor
(seeApplicationAdminPermission(ApplicationDescriptor, String)
) - The
filter
of this permission mathes theApplicationDescriptor
specified in theotherPermission
. If the filter in this permission is the<<SELF>>
pseudo target, then the currentApplicationId set in theotherPermission
is compared to the application Id of the targetApplicationDescriptor
. - The list of permitted actions in this permission contains all actions required in the
otherPermission
- Specified by:

- Parameters:
