It then calls -- various dispatching and class-wide subprograms using those objects. -- The packages in F393A00 are instrumented to trace the flow of -- execution. -- The test checks for the correct order of execution, as expected -- by the various calls. -- -- TEST FILES: -- The following files comprise this test: -- -- F393A00.A (foundation code) -- C393A02.A -- -- -- CHANGE HISTORY: -- 06 Dec 94 SAIC ACVC 2.0 -- 19 Dec 94 SAIC Removed RM references from objective text. -- 05 APR 96 SAIC Update RM references for 2.1 -- --! with Report; with F393A00_0; with F393A00_1; with F393A00_2; with F393A00_3; with F393A00_4; procedure C393A02 is A_Windmill : F393A00_2.Windmill; A_Pump : F393A00_3.Pump; A_Mill : F393A00_4.Mill; A_Windmill_2 : F393A00_2.Windmill; A_Pump_2 : F393A00_3.Pump; A_Mill_2 : F393A00_4.Mill; B_Windmill : F393A00_2.Windmill; B_Pump : F393A00_3.Pump; B_Mill : F393A00_4.Mill; procedure Swapem( A,B: in out F393A00_2.Windmill'Class ) is begin F393A00_0.TC_Touch('x'); F393A00_2.Swap( A,B ); end Swapem; function Zephyr( A: F393A00_2.Windmill'Class ) return F393A00_2.Windmill'Class is Item : F393A00_2.Windmill'Class := A; begin F393A00_0.TC_Touch('y'); if not F393A00_1.Initialized( Item ) then -- b F393A00_2.Initialize( Item ); -- a end if; F393A00_2.Stop( Item ); -- f / mff F393A00_2.Add_Spin( Item, 10 ); -- e return Item; end Zephyr; function Gale( It: F393A00_2.Windmill ) return F393A00_2.Windmill'Class is Item : F393A00_2.Windmill'Class := It; begin F393A00_2.Stop( Item ); -- f F393A00_2.Add_Spin( Item, 40 ); -- e return Item; end Gale; function Gale( It: F393A00_3.Pump ) return F393A00_2.Windmill'Class is Item : F393A00_2.Windmill'Class := It; begin F393A00_2.Stop( Item ); -- f F393A00_2.Add_Spin( Item, 50 ); -- e return Item; end Gale; function Gale( It: F393A00_4.Mill ) return F393A00_2.Windmill'Class is Item : F393A00_2.Windmill'Class := It; begin F393A00_2.Stop( Item ); -- mff F393A00_2.Add_Spin( Item, 60 ); -- e return Item; end Gale; begin -- Main test procedure.
