public:

%Docstring
|

Initialize path resolver with a base filename. Null filename means no conversion between relative/absolute path

%End

QString writePath( const QString &filename ) const;

%Docstring
|
|
Prepare a filename to save it to the project file.
|
|
Creates an absolute or relative path according to the project settings.
|
|
Paths written to the project file should be prepared with this method.

Turn filename read from the project file to an absolute path

static QString setPathPreprocessor( SIP_PYCALLABLE / AllowNone / );
|
|
%Docstring
|
|
Sets a path pre-processor function, which allows for manipulation of paths and data sources prior
|
|
to resolving them to file references or layer sources.
|
|
|
|
The ``processor`` function must accept a single string argument (representing the original file path
|
|
or data source), and return a processed version of this path.
|
|
|
|
The path pre-processor function is called before any bad layer handler.
|
|
|
|
If multiple preprocessors are set, they will be called in sequence based on the order in which
|
|
they were originally set.
|
|
|
|
Example - replace an outdated folder path with a new one:
|
|
|
|
.. code-block:: python
|
|
|
|
def my_processor(path):
|
|
return path.replace('c:/Users/ClintBarton/Documents/Projects', 'x:/Projects/')
|
|
|
|
QgsPathResolver.setPathPreprocessor(my_processor)
|
|
|
|
Example - replace a stored database host with a new one:
|
|
|
|
.. code-block:: python
|
|
|
|
def my_processor(path):
|
|
return path.replace('host=10.1.1.115', 'host=10.1.1.116')
|
|
|
|
QgsPathResolver.setPathPreprocessor(my_processor)
|
|
|
|
Example - replace stored database credentials with new ones:
|
|
|
|
.. code-block:: python
|
|
|
|
def my_processor(path):
|
|
path = path.replace("user='gis_team'", "user='team_awesome'")
|
|
path = path.replace("password='cats'", "password='g7as!m*'")
|
|
return path
