This is followed by an integer object containing a count of -- the number of service months for the customer. Finally, a -- two-dimensional array object with monthly consumption information for -- the customer is written to the stream. -- -- Objects of record types with discriminants without defaults should -- have their discriminants included in the stream when using 'Output. -- Likewise, discriminants should be extracted -- from the stream when using 'Input. Similarly, array bounds are written -- to and read from the stream when using 'Output and 'Input with array -- objects. -- -- APPLICABILITY CRITERIA: -- Applicable to all implementations that support external -- Stream_IO files. -- -- -- CHANGE HISTORY: -- 06 Dec 94 SAIC ACVC 2.0 -- --! with FXACB00; with Ada.Streams.Stream_IO; with Report; procedure CXACB01 is begin Report.Test ("CXACB01", "Check that the default attributes 'Input and " & "'Output work properly when used with objects " & "of record, natural, and array types" ); Test_for_Stream_IO_Support: declare Util_File : Ada.Streams.Stream_IO.File_Type; Util_Stream : Ada.Streams.Stream_IO.Stream_Access; Utility_Service_Filename : constant String := Report.Legal_File_Name; begin -- If an implementation does not support Stream_IO in a particular -- environment, the exception Use_Error or Name_Error will be raised on -- calls to various Stream_IO operations.
