Python bindings

These are bindings on the CParameterMgrFullConnector class, its inner Ilogger class and both classes involved in the SelectionCriterion creation.

They are complete enough to write a parameter-framework client in Python and also access most of the tuning interface.

Generation

The bindings are defined unsing SWIG in the pfw.i file and the actual source files are generated by the command found in regen_swig.sh. This command must be re-run whenever any file in parameter/include is modified.

Two things are generated:

  • A C++ source file providing a low-level wrapping of the parameter-framework classes. When compiled as a shared library, it can be imported from Python as a module called _PyPfw but this module is not for direct use.
  • A Python module called PyPfw, using PyPfw, providing proxy classes of the parameter-framework's native classes. Please not that in the context of the Python bindings, the CParameterMgrFullConnector class is renamed ParameterFramework.

Usage

sample.py provides an example of how to use the PyPfw module. Note that the PYTHONPATH env variable must contain the directory of both _PyPfw.so and PyPfw.py.
