The Storage_IO subprograms, Read and Write, --- demonstrated in this scenario, perform tag "fixing" prior to/following --- transfer to the Direct_IO files. --- This method is especially important for those implementations that --- represent tags as pointers, or for cases where the tagged objects --- are read in by a program other than the one that wrote them. --- --- In this small example, we have attempted to simulate the situation --- where two independent programs are using a series of Direct_IO files, --- one writing data to the files, and the second program reading the --- data from those files. Two procedures are defined, the first --- simulating the program responsible for writing, the second simulating --- a separate program opening and reading the data from the files. --- --- The hierarchy of types used in this test can be displayed as follows: --- --- Account_Type --- / \ --- / \ --- / \ --- Cash_Account_Type Investment_Account_Type --- / \ --- / \ --- / \ --- Checking_Account_Type Savings_Account_Type --- --- APPLICABILITY CRITERIA: --- Applicable to implementations capable of supporting external --- Direct_IO files. --- --- --- CHANGE HISTORY: --- 06 Dec 94 SAIC ACVC 2.0 --- 08 Nov 95 SAIC Corrected incorrect prefix of 'Tag for ACVC 2.0.1, --- and mode of files in Procedure Read_Data. --- Added verification of objects reconstructed from --- files. --- 27 Feb 97 PWB.CTA Allowed for non-support of some IO operations ---! - -package CXA9002_0 is - - type Investment_Type is (Stocks, Bonds, Mutual_Funds); - type Savings_Type is (Standard, Business, Impound); - - type Account_Type is tagged - record - Num : String (1..3); - end record; - - type Cash_Account_Type is new Account_Type with - record - Years_As_Customer : Natural := 1; - end record; - - type Investment_Account_Type is new Account_Type with - record - Investment_Vehicle : Investment_Type := Stocks; - end record; - - type Checking_Account_Type is new Cash_Account_Type with - record - Checks_Per_Year : Positive := 200; - Interest_Bearing : Boolean := False; - end record; - - type Savings_Account_Type is new Cash_Account_Type with - record - Kind : Savings_Type := Standard; - end record; - -end CXA9002_0; - ---- - -with Report; -with Ada.Storage_IO; -with Ada.Direct_IO; -with Ada.Tags; -with CXA9002_0; - -procedure CXA9002 is - package Dir_IO is new Ada.Direct_IO (Integer); - Test_File : Dir_IO.File_Type; - Incomplete : exception; -begin - - Report.Test ("CXA9002", "Check that the operations defined in the " & - "generic package Ada.Storage_IO provide the " & - "ability to store and retrieve objects of " & - "tagged types from in-memory buffers"); - - - Test_For_Direct_IO_Support: - begin - - -- The following Create does not have any bearing on the test scenario, - -- but is included to check that the implementation supports Direct_IO - -- files.
