ExporterRegistry

General

ExporterRegistry és una classe en Aspose.Slides FOSS per a C++.

Registre central per als exportadors de format. Manten un mapping des de les cadenes de valors SaveFormat a les seves fàbriques d’exportador corresponents. Els nous exportadores es poden registrar dinàmicament, fent més fàcil afegir nous formats d ’exportació. @code // Registrar un exportador ExporterRegistry::register_exporter (); // Obtén un exporter per a un format auto-exportator = ExporterRegistry get_xporter ((“Pptx “); si (exportador) { exportadora->export_presentation ((package, “output.pptx”); } @endcode

`get_exporter_class(format_value: std::string_view)` → `std::optional<ExporterFactory>`	Returns an optional containing the factory for the format, if registered
`is_format_supported(format_value: std::string_view)` → `bool`	Check if a format has a registered exporter.
`get_supported_formats()` → `std::vector<std::string>`	Register an exporter class for its supported formats. Calls T::get_supported_formats() to discover which format strings the exporter handles, then maps each to a factory that creates T.
