Declare a generic package which --- operates on lists of elements of integer types. Declare a generic --- child of this package which defines additional list operations. --- Use the formal discrete type as the generic formal actual part for the --- parent formal package. --- --- Declare an instance of parent, then declare an instance of the child --- which is itself a child the parent's instance. In the main program, --- check that the operations in both instances perform as expected. --- --- --- CHANGE HISTORY: --- 06 Dec 94 SAIC ACVC 2.0 --- 15 Nov 95 SAIC Update and repair for ACVC 2.0.1 --- 07 Sep 96 SAIC Change formal param E to be out only. --- 19 Oct 96 SAIC ACVC 2.1: Added pragma Elaborate to context --- clauses of CA11014_0, CA11014_1, and CA11014_5. --- 27 Feb 97 PWB.CTA Added elaboration pragma at package CA11014_4 ---! - --- Actual package for the parent's formal. -generic - - type Element_Type is (<>); -- List elems may be of any discrete types. - -package CA11014_0 is - - type Node_Type; - type Node_Pointer is access Node_Type; - - type Node_Type is record - Item : Element_Type; - Next : Node_Pointer := null; - end record; - - type List_Type is record - First : Node_Pointer := null; - Current : Node_Pointer := null; - Last : Node_Pointer := null; - end record; - - -- Return true if current element is last in the list. - function End_Of_List (L : List_Type) return boolean; - - -- Set "current" pointer to first list element. - procedure Reset (L : in out List_Type); - -end CA11014_0; - - --==================================================================-- - -package body CA11014_0 is - - function End_Of_List (L : List_Type) return boolean is - begin - return (L.Current = null); - end End_Of_List; - ------------------------------------------------------- - procedure Reset (L : in out List_Type) is - begin - L.Current := L.First; -- Set "current" pointer to first - end Reset; -- list element. - -end CA11014_0; - - --==================================================================-- - -with CA11014_0; -- Generic list abstraction. -pragma Elaborate (CA11014_0); -generic - - -- Import the list abstraction defined in CA11014_0. - with package List_Mgr is new CA11014_0 (<>); - -package CA11014_1 is - - -- Write to current element and advance "current" pointer. - procedure Write_Element (L : in out List_Mgr.List_Type; - E : in List_Mgr.Element_Type); - - -- Read from current element and advance "current" pointer. - procedure Read_Element (L : in out List_Mgr.List_Type; - E : out List_Mgr.Element_Type); - - -- Add element to end of list. - procedure Add_Element (L : in out List_Mgr.List_Type; - E : in List_Mgr.Element_Type); - -end CA11014_1; - - --==================================================================-- - -package body CA11014_1 is - - procedure Write_Element (L : in out List_Mgr.List_Type; - E : in List_Mgr.Element_Type) is - begin - L.Current.Item := E; -- Write to current element. - L.Current := L.Current.Next; -- Advance "current" pointer. - end Write_Element; - ------------------------------------------------------- - procedure Read_Element (L : in out List_Mgr.List_Type; - E : out List_Mgr.Element_Type) is - begin - E := L.Current.Item; -- Retrieve current element. - L.Current := L.Current.Next; -- Advance "current" pointer. - end Read_Element; - ------------------------------------------------------- - procedure Add_Element (L : in out List_Mgr.List_Type; - E : in List_Mgr.Element_Type) is - New_Node : List_Mgr.Node_Pointer := new List_Mgr.Node_Type'(E, null); - use type List_Mgr.Node_Pointer; - begin - if L.First = null then -- No elements in list, so add new - L.First := New_Node; -- element at beginning of list. - else - L.Last.Next := New_Node; -- Add new element at end of list. - end if; - L.Last := New_Node; -- Set last-in-list pointer. - end Add_Element; - -end CA11014_1; - - --==================================================================-- - --- Generic child of list operation.
