* [feature] support datasets with data defined on faces in mesh calculator, fix #30219, fix #30170 added "driver" and "group name" to the calculator interface. MDAL now supports 3 drivers for storing results, so user must be able to choose appropriate driver and dataset group name (some drivers store multiple groups to 1 file)

Holds data provider key, description, and associated shared library file or function pointer information.
|
|
|
|
Provider metadata refers either to providers which are loaded via libraries or
|
|
which are native providers that are included in the core QGIS installation
|
|
and accessed through function pointers.
|
|
|
|
For library based providers, the metadata class is used in a lazy load
|
|
implementation in :py:class:`QgsProviderRegistry`. To save memory, data providers
|
|
are only actually loaded via QLibrary calls if they're to be used. (Though they're all
|
|
iteratively loaded once to get their metadata information, and then
|
|
unloaded when the QgsProviderRegistry is created.) :py:class:`QgsProviderMetadata`
|
|
supplies enough information to be able to later load the associated shared
|
|
library object.
