Class ApplicationAdminPermission

  • All Implemented Interfaces:
    java.io.Serializable, java.security.Guard
    public class ApplicationAdminPermission
extends java.security.Permission
    This class implements permissions for manipulating applications and their instances.

    ApplicationAdminPermission can be targeted to applications that matches the specified filter.

    ApplicationAdminPermission may be granted for different actions: lifecycle, schedule and lock. The permission schedule implies the permission lifecycle.

      • ApplicationAdminPermission

        public ApplicationAdminPermission​(java.lang.String filter,
                                  java.lang.String actions)
                           throws org.osgi.framework.InvalidSyntaxException
        Constructs an ApplicationAdminPermission. The filter specifies the target application. The filter is an LDAP-style filter, the recognized properties are signer and pid. The pattern specified in the signer 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 attribute pid is matched with the PID of the application according to the filter string rules.

        If the filter is null then it matches "*". If actions is "*" then it identifies all the possible actions.

        Parameters:
        filter - filter to identify application. The value null 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 be null. The order of the actions in the list is not significant.
        Throws:
        org.osgi.framework.InvalidSyntaxException - is thrown if the specified filter is not syntactically correct.
        java.lang.NullPointerException - is thrown if the actions parameter is null

        public ApplicationAdminPermission​(ApplicationDescriptor application,
                                  java.lang.String actions)
        This constructor should be used when creating ApplicationAdminPermission instance for checkPermission call.
        Parameters:
        application - The target of the operation, it must not be null.
        actions - The required operation, it must not be null.
        Throws:
        java.lang.NullPointerException - If any of the arguments is null.

    • Method Detail

      • setCurrentApplicationId

        public ApplicationAdminPermission setCurrentApplicationId​(java.lang.String applicationId)
        This method can be used in the ProtectionDomain implementation in the implies 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

        public boolean implies​(java.security.Permission otherPermission)
        Checks if the specified permission 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))
        • The implied otherPermission was created for a particular ApplicationDescriptor (see ApplicationAdminPermission(ApplicationDescriptor, String))
        • The filter of this permission matches the ApplicationDescriptor specified in the otherPermission. If the filter in this permission is the <<SELF>> pseudo target, then the currentApplicationId set in the otherPermission is compared to the application Id of the target ApplicationDescriptor.
        • The list of permitted actions in this permission contains all actions required in the otherPermission
        Otherwise the method returns false.
        Specified by:
        implies in class java.security.Permission
        Parameters:
        otherPermission - the implied permission
        Returns:
        true if this permission implies the otherPermission, false otherwise.

      • equals

        public boolean equals​(java.lang.Object with)
        Specified by:
        equals in class java.security.Permission

      • equal

        private static boolean equal​(java.lang.Object a,
                             java.lang.Object b)
        Compares parameters for equality. If both object are null, they are considered equal.
        Parameters:
        a - object to compare
        b - other object to compare
        Returns:
        true if both objects are equal or both are null

        Returns:
        the actions specified when this permission was created
