* Eliminate duplicate overrides of Converter methods in exampleEdward Welbourne2023-11-011-5/+0
| | | | | | | | | | | | | | | | | The Out-only converters shouldn't need to implement loadFile(), as it shouldn't be called - a converter is not used for input unless it says it supports input. At the same time, provide the "ground state" implementations for optionsHelp(), outputOptions() and probeFile() to save the trivial implementations the need to duplicate one another. In the process, make the handling of loadFile()'s outputConverter more consistent among those that do implement it. Always set outputConverter if it's initially null (the caller does assert this). Pick-to: 6.6 6.5 Task-number: QTBUG-111228 Change-Id: I856d12c791d1f8e0accdb7dd1412d493117b2302 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* Replace confusing member variable with a predicateEdward Welbourne2023-11-011-1/+1
| | | | | | | | | | | | | | | | | | | The Converter class, in the eponymous example, had a null member variable that wasn't a nullptr - it pointed to an instance of NullConverter - so that other converters could test whether a Converter * they'd been passed was null (in the sense of pointing to a NullConverter). This, however, was susceptible to misreading - I misread one such comparison as a nullptr check and thus thought it redundant with an earlier actual nullptr check. To spare future readers similar confusion, replace the public static member variable with a protected (since only other derived classes need it) static predicate, to at least give the reader a clue that this is using the word null in a class-specific sense.

* Convert fprintf(stderr, ...); exit(EXIT_FAILURE); to qFatal(...)Edward Welbourne2023-10-301-10/+6
| | | | | | | | | | | | The serialization conversion example used raw C's way to abort on error; change to using Qt's way of doing the same. Likewise, convert the various other uses of fprintf(stderr, ...) to qWarning() and of printf(...) to qInfo().

* Serialization converter example: const-ify the Converter typeEdward Welbourne2023-09-081-7/+8
| | | | | | | | | | | | Its methods act on their parameters without changing the converter, so can all be const. Its instances thus have no non-const members to exercise, so can always be const.

* corelib/serialization examples: clang-tidy and coding style clean-upEdward Welbourne2023-09-081-6/+1
| | | | | | | | | | | | I overrode clang-tidy where it uglified or obfuscated and did some clean-up provoked or made possible by its changes. Konrad pointed out, in review, a constructor that could be = default; it could, in fact, vanish entirely as a result.

* corelib/serialization examples: use string literals moreEdward Welbourne2023-09-081-4/+6
| | | | | | | | | | | | A couple more compilation units could use Qt::StringLiterals. Prefer QL1SV for the code constants, to keep code small. Convert fpToString() to take QL1SV instead of const char *, with suffix empty by default. Also rearranged some spacing, some if it suggested by clang-tidy.
