/** \ingroup core
|
|
* Holds data provider key, description, and associated shared library file information.
|
|
|
|
The metadata class is used in a lazy load implementation in
|
|
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.) QgsProviderMetadata
|
|
supplies enough information to be able to later load the associated shared
|
|
library object.
