    • 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.
