blocklisted and hidden from the QGIS interface, e.g. it is an internal detail only (or sidecar file) and shouldn't be shown in things like the browser panel And adds blocklists for .aux.xml, .shp.xml and .tif.xml files for the ogr/gdal providers

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.

|

Returns an integer representing the priority which this provider should have when opening

a dataset with the specified ``uri``.
|

A larger priority means that the provider should be selected over others with a lower

Returns ``True`` if the specified ``uri`` is known by this provider to be something which should
|
|
be blocklisted from the QGIS interface, e.g. an internal detail only.
|
|
|
|
Specifically, this method can be utilised by the browser panel to hide noisy internal details
|
|
by returning ``True`` for URIs which are known to be sidecar files only, such as ".aux.xml" files
|
|
or ".shp.xml" files, or the "ept-build.json" files which sit alongside Entwine "ept.json" point
|
|
cloud sources.
|
|
|
|
The default method returns ``False`` for all URIs.
|
|
|
|
.. warning::
|
|
|
|
Returning ``True`` from an implementation of this method indicates that ALL providers should
|
|
ignore the specified ``uri``, not just the provider associated with this metadata!
