Force the entry call to be --- queued by having the task call a procedure, prior to the corresponding --- accept statement, which simulates a routine waiting for user input --- (with a delay). --- --- Simulate a time-consuming routine in the abortable part by calling a --- procedure containing an infinite loop. Meanwhile, simulate input by --- the user (the delay expires) which is NOT the input expected by the --- guard on the accept statement. The entry remains closed, and the --- task completes its execution. Since the entry was not accepted before --- its task completed, Tasking_Error is raised at the point of the entry --- call. --- --- --- CHANGE HISTORY: --- 06 Dec 94 SAIC ACVC 2.0 --- ---! - -package C974005_0 is -- Automated teller machine abstraction. - - - -- Flags for testing purposes: - - Count : Integer := 1234; - - type Key_Enum is (None, Cancel, Deposit, Withdraw); - - type Card_Number_Type is private; - type Card_PIN_Type is private; - type ATM_Card_Type is private; - - - Transaction_Canceled : exception; - - - task type ATM_Keyboard_Task is - entry Cancel_Pressed; - end ATM_Keyboard_Task; - - - procedure Read_Card (Card : in out ATM_Card_Type); - - procedure Validate_Card (Card : in ATM_Card_Type); - - procedure Perform_Transaction (Card : in ATM_Card_Type); - -private - - type Card_Number_Type is range 1 .. 9999; - type Card_PIN_Type is range 100 .. 999; - - type ATM_Card_Type is record - Number : Card_Number_Type; - PIN : Card_PIN_Type; - end record; - -end C974005_0; - - - --==================================================================-- - - -with Report; -with ImpDef; - -package body C974005_0 is - - - procedure Listen_For_Input (Key : out Key_Enum) is - begin - -- Simulate the situation where a user waits a bit for the card to - -- be validated, then presses a transaction key (NOT Cancel). - - -- Delay long enough to force queuing of Keyboard.Cancel_Pressed. - delay ImpDef.Clear_Ready_Queue; - - if Report.Equal (3, 3) then -- Always true. - Key := Deposit; -- Cancel is NOT pressed. - end if; - end Listen_For_Input; - - - task body ATM_Keyboard_Task is - Key_Pressed : Key_Enum := None; - begin - - -- Note: no loop.
