| -- |
| -- OBJECTIVE: |
| -- Check that the default attributes 'Write and 'Read work properly when |
| -- used with objects of a variety of types, including records with |
| -- default discriminants, records without default discriminants, but |
| -- which have the discriminant described in a representation clause for |
| -- the type, and arrays. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test simulates a basic sales record system, using Stream_IO to |
| -- allow the storage of heterogeneous data in a single stream file. |
| -- |
| -- Four types of data are written to the stream file for each product. |
| -- First, the "header" information on the product is written. |
| -- This is an object of a discriminated (with default) record |
| -- type. This is followed by an integer object containing a count of |
| -- the number of sales data records to follow. The corresponding number |
| -- of sales records follow in the stream. These are of a record type |
| -- with a discriminant without a default, but where the discriminant is |
| -- included in the representation clause for the type. Finally, an |
| -- array object with statistical sales information for the product is |
| -- written to the stream. |
| -- |
| -- Objects of both record types specified below (discriminated records |
| -- with defaults, and discriminated records w/o defaults that have the |
| -- discriminant included in a representation clause for the type) should |
| -- have their discriminants included in the stream when using 'Write. |
| -- Likewise, discriminants should be extracted from the stream when |
| -- using 'Read. |
| -- |
| -- APPLICABILITY CRITERIA: |
| -- Applicable to all implementations that support external |
| -- Stream_IO files. |
