    • Method Detail

      • implies

        public boolean implies(Permission p)
        Checks if the specified permission is "implied" by this object.

        More specifically, this method returns true if:

        • p's class is the same as this object's class, and
        • p's name equals or (in the case of wildcards) is implied by this object's name. For example, "a.b.*" implies "a.b.c".
        Specified by:
        implies in class Permission
        Parameters:
        p - the permission to check against.
        Returns:
        true if the passed permission is equal to or implied by this permission, false otherwise.
      • equals

        public boolean equals(Object obj)
        Checks two BasicPermission objects for equality. Checks that obj's class is the same as this object's class and has the same name as this object.

        Specified by:
        equals in class Permission
        Parameters:
        obj - the object we are testing for equality with this object.
        Returns:
        true if obj's class is the same as this object's class and has the same name as this BasicPermission object, false otherwise.

      • getActions

        public String getActions()
        Returns the canonical string representation of the actions, which currently is the empty string "", since there are no actions for a BasicPermission.
        Specified by:
        getActions in class Permission
        Returns:
        the empty string "".
      • newPermissionCollection

        public PermissionCollection newPermissionCollection()
        Returns a new PermissionCollection object for storing BasicPermission objects.

        BasicPermission objects must be stored in a manner that allows them to be inserted in any order, but that also enables the PermissionCollection implies method to be implemented in an efficient (and consistent) manner.

        Overrides:
        newPermissionCollection in class Permission
        Returns:
        a new PermissionCollection object suitable for storing BasicPermissions.
