Check that each derivative inherits all user- -- defined primitive subprograms of its parent (including those that -- its parent inherited), and that it may declare its own primitive -- subprograms. -- -- Check that predefined equality operators are defined for the root -- tagged type. -- -- Check that type conversion is defined from a type extension to its -- parent, and that this parent itself may be a type extension. -- -- TEST DESCRIPTION: -- Declare a root tagged type in a package specification. Declare two -- primitive subprograms for the type. -- -- Extend the root type with a record extension in the same package -- specification. Declare a new primitive subprogram for the extension -- (in addition to its two inherited subprograms). -- -- Extend the extension with a record extension in the same package -- specification. Declare a new primitive subprogram for this second -- extension (in addition to its three inherited subprograms). -- -- In the main program, declare operations for the root tagged type which -- utilize aggregates and equality operators to verify the correctness -- of the components. Overload these operations for the two type -- extensions. Within each of these overloading operations, utilize type -- conversion to call the parent's implementation of the same operation. -- -- TEST FILES: -- The following files comprise this test: -- -- C3900010.A -- => C3900011.AM -- -- -- CHANGE HISTORY: -- 06 Dec 94 SAIC ACVC 2.0 -- --! with C3900010; with Report; procedure C3900011 is package Check_Alert_Values is -- Declare functions to verify correctness of tagged record components -- before and after calls to their primitive subprograms. -- Alert_Type: function Initial_Values_Okay (A : in C3900010.Alert_Type) return Boolean; function Bad_Final_Values (A : in C3900010.Alert_Type) return Boolean; -- Low_Alert_Type: function Initial_Values_Okay (LA : in C3900010.Low_Alert_Type) return Boolean; function Bad_Final_Values (LA : in C3900010.Low_Alert_Type) return Boolean; -- Medium_Alert_Type: function Initial_Values_Okay (MA : in C3900010.Medium_Alert_Type) return Boolean; function Bad_Final_Values (MA : in C3900010.Medium_Alert_Type) return Boolean; end Check_Alert_Values; --==========================================================-- package body Check_Alert_Values is function Initial_Values_Okay (A : in C3900010.Alert_Type) return Boolean is use type C3900010.Alert_Type; begin -- "=" operator availability. return (A = (Arrival_Time => C3900010.Default_Time, Display_On => C3900010.Null_Device)); end Initial_Values_Okay; function Initial_Values_Okay (LA : in C3900010.Low_Alert_Type) return Boolean is begin -- Type conversion. return (Initial_Values_Okay (C3900010.Alert_Type (LA)) and LA.Level = 0); end Initial_Values_Okay; function Initial_Values_Okay (MA : in C3900010.Medium_Alert_Type) return Boolean is use type C3900010.Person_Enum; begin -- Type conversion. return (Initial_Values_Okay (C3900010.Low_Alert_Type (MA)) and MA.Action_Officer = C3900010.Nobody); end Initial_Values_Okay; function Bad_Final_Values (A : in C3900010.Alert_Type) return Boolean is use type C3900010.Alert_Type; begin -- "/=" operator availability. return (A /= (Arrival_Time => C3900010.Alert_Time, Display_On => C3900010.Null_Device)); end Bad_Final_Values; function Bad_Final_Values (LA : in C3900010.Low_Alert_Type) return Boolean is use type C3900010.Low_Alert_Type; begin -- "=" operator availability. return not ( LA = (Arrival_Time => C3900010.Alert_Time, Display_On => C3900010.Teletype, Level => 1) ); end Bad_Final_Values; function Bad_Final_Values (MA : in C3900010.Medium_Alert_Type) return Boolean is use type C3900010.Medium_Alert_Type; begin -- "/=" operator availability. return ( MA /= (C3900010.Alert_Time, C3900010.Console, 1, C3900010.Duty_Officer) ); end Bad_Final_Values; end Check_Alert_Values; --==========================================================-- use Check_Alert_Values; use C3900010; Root_Alarm : C3900010.Alert_Type; Low_Alarm : C3900010.Low_Alert_Type; Medium_Alarm : C3900010.Medium_Alert_Type; begin Report.Test ("C390001", "Primitive operation inheritance by type " & "extensions: all extensions declared in same package " & "as parent"); -- Check root tagged type: if Initial_Values_Okay (Root_Alarm) then Handle (Root_Alarm); -- Explicitly declared.
