|
26 -- OBJECTIVE:
|
|
|
27 -- Check that the version of Ada.Text_IO.Editing.Put with an out
|
|
|
28 -- String parameter propagates Layout_Error if the edited output string
|
|
|
29 -- result of Put exceeds the length of the out String parameter.
|
|
|
30 --
|
|
|
31 -- TEST DESCRIPTION:
|
|
|
32 -- This test is structured using tables of data, consisting of
|
|
|
33 -- numerical values, picture strings, and expected image
|
|
|
34 -- result strings. These data tables are found in package FXF3A00.
|
|
|
35 --
|
|
|
36 -- This test examines the case of the out string parameter to Procedure
|
|
|
37 -- Put being insufficiently long to hold the entire edited output
|
|
|
38 -- string result of the procedure. In this case, Layout_Error is to be
|
|
|
39 -- raised. Test failure results if Layout_Error is not raised, or if an
|
|
|
40 -- exception other than Layout_Error is raised.
|
|
|
41 --
|
|
|
42 -- A number of data combinations are examined, using instantiations
|
|
|
43 -- of Package Decimal_Output with different decimal data types and
|
|
|
44 -- both default and non-default parameters as generic actual parameters.
|
|
|
45 -- In addition, calls to Procedure Put are performed using default
|
|
|
46 -- parameters, non-default parameters, and non-default parameters that
|
|
|
47 -- override the generic actual parameters provided at the time of
|
|
|
48 -- instantiation of Decimal_Output.
