This method will be called whenever the project tries to load layers
|
|
which cannot be accessed. It should inform the user about this and if
|
|
possible offer to fix the unavailable layers by setting a valid
|
|
datasource, e.g. by showing a file dialog.
|
|
|
|
The default implementation will dismiss all bad layers and write
|
|
information to the log.

Returns data type associated with the given :py:class:`QgsProject` file

The Dom node should represent the state associated with a specific

layer.

Returns the data source for the given layer

The QDomNode is a :py:class:`QgsProject` Dom node corresponding to a map
|
|
layer state.
|
|
|
|
Essentially dumps datasource tag.

%Docstring

Returns the physical storage type associated with the given layer
|
|
|
|
The QDomNode is a :py:class:`QgsProject` Dom node corresponding to a map
|
|
layer state.
|
|
|
|
If the provider tag is "ogr", then it's a file type.
|
|
|
|
However, if the layer is a raster, then there won't be a provider tag.
|
|
It will always have an associated file.
|
|
|
|
If the layer doesn't fall into either of the previous two categories,
|
|
then it's either a database or URL. If the datasource tag has "url=",
|
|
then it's URL based and if it has "dbname=">, then the layer data is in
|
|
a database.
