GRBModel.write()

This method is the general entry point for writing model data to a file. It can be used to write optimization models, IIS submodels, solutions, basis vectors, MIP start vectors, or parameter settings. The type of file is determined by the file suffix. File formats are described in the File Format section.

Note that writing a model to a file will process all pending model modifications. However, writing other model information (solutions, bases, etc.) will not.

void write ( String filename )

    Arguments:

    filename: Name of the file to write. The file type is encoded in the file name suffix. Valid suffixes for writing the model itself are .mps, .rew, .lp, or .rlp. An IIS can be written by using an .ilp suffix. Use .sol for a solution file, .mst for a MIP start, .hnt for MIP hints, .bas for a basis file, or .prm for a parameter file. The suffix may optionally be followed by .gz, .bz2, or .7z, which produces a compressed result.
