- update methods of existing classes - add comment to methods missing in the sip bindings - split up collective sip files into single files and use same directory structure in python/ as in src/ - add a lot of missing classes (some might not make sense because of missing python methods in those classes) - remove some non-existing methods from the header files - add scripts/sipdiff - replace some usages of std::vector and std::set with QVector/QSet

/** 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.
