API Reference

All public namespaces and classes grouped by namespace.

About this Reference

This page lists all known public classes grouped by namespace, with links to their header files. For detailed documentation on individual classes, see the Classes section. Status badges reflect the implementation state from Doxygen comments in source files. Public System/* include spellings are stable; the paths below identify the physical module owner where one namespace has a single owner. See Components & Modules when an API area spans multiple components.
