Check that --- the visible part of the generic formal package includes the first list --- of basic declarative items of the package specification. --- --- TEST DESCRIPTION: --- Declare a list abstraction in a generic package which manages lists of --- elements of any nonlimited type. Declare a generic child package of --- this package which defines additional list operations. Declare a --- generic subprogram which operates on lists of elements of discrete --- types. Provide the generic subprogram with three formal parameters: --- (1) a formal discrete type which represents a list element type, (2) --- a generic formal package with the parent list generic as template, and --- (3) a generic formal package with the child list generic as template. --- Use the formal discrete type as the generic formal actual part for the --- parent formal package. In the main program, declare an instance of --- parent, then declare an instance of the child which is itself a child --- the parent's instance. Pass these instances as actuals to the generic --- subprogram instance. --- --- --- CHANGE HISTORY: --- 06 Dec 94 SAIC ACVC 2.0 --- 05 Nov 95 SAIC ACVC 2.0.1 fixes: Corrected syntax of formal --- package declaration. --- 27 Feb 97 PWB.CTA Added an elaboration pragma. ---! - -generic - type Element_Type is private; -- List elems may be of any nonlimited type. -package CC70001_0 is -- List abstraction. - - type List_Type is limited private; - - - -- 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); - -private - - type Node_Type; - type Node_Pointer is access Node_Type; - - type Node_Type is record - Item : Element_Type; - Next : Node_Pointer; - end record; - - type List_Type is record - First : Node_Pointer; - Current : Node_Pointer; - Last : Node_Pointer; - end record; - -end CC70001_0; - - - --==================================================================-- - - -package body CC70001_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 CC70001_0; - - - --==================================================================-- - - --- Child must be generic since parent is generic.
