Extending the interface

PySCIPOpt already covers many of the SCIP callable library methods. You may also extend it to increase the functionality of this interface. The following will provide some directions on how this can be achieved:

The two most important files in PySCIPOpt are the scip.pxd and scip.pyx. These two files specify the public functions of SCIP that can be accessed from your python code.

To make PySCIPOpt aware of the public functions you would like to access, you must add them to scip.pxd. There are two things that must be done in order to properly add the functions:

1. Ensure any enums, structs or SCIP variable types are included in scip.pxd
2. Add the prototype of the public function you wish to access to scip.pxd

After following the previous two steps, it is then possible to create functions in python that reference the SCIP public functions included in scip.pxd. This is achieved by modifying the scip.pyx file to add the functionality you require.
