Hi all,
I have stomped into above error and I am stuck with the error and
runtime exception PROGRAM_ERROR : accessibility check failed.
Here's the fragment of my codes:
generic
N : Positive;
type Item is private;
package High_Cloud is
package List renames Heterogeneous_Doubly_Link_List;
use List;
type Data_Array is array ( 1 .. N ) of Item;
type Element_Record is new List.Node with private;
type Series_Access is new List.Access_List;
private
type Element_Record is new List.Node with
record
Name : Unbounded_String;
Color : Unbounded_String;
Data : Data_Array;
end record;
...
end High_Cloud;
In the package body of High_Cloud, I have a procedure:
procedure Add
( Cloud : in out High_Cloud_Record;
Name : in Unbounded_String;
Color : in Unbounded_String;
Data : in Data_Array )
is
New_Element : List.Access_Node;
begin
New_Element := new Element_Record'
<========== Error/Warning here.
( Constructor.Init ( Name, Color, Data) ) ;
Concatenate ( Cloud.Series, New_Element ) ;
end Add;
My intention is to use genericity to create a data which is an array
(1..N) of any_type. This data is then stored in a list. Procedure Add
instantiate (by calling to Constructor.Init) the list's node with
data.
I have read the ARM 3.10.2 and 3.10.1 and also John Barnes book yet I
still have no clue how to solve the problem.
Can you please help? Thanks.
