How to migrate

Significant API changes have been made between version 7.x and 8.x of MEDCoupling. This page guides you through the changes you have to apply to migrate.

First of all, the script

medcoup7to8.py

installed in the binary directory can do most of the job. It takes as first argument the path of the directory containing the sources you want to port. Only some extensions are handled. A backup of the modified files is done. Run

medcoup7to8.py --help

for a full usage description, including the handled file extensions.

Beware however that the two substitutions below can not be done via this script, because they might conflict with standard STL C++ functions:

  • DataArray*::search -> DataArray*::findIdSequence
  • DataArray*::substr -> DataArray*::subArray Those will have to be treated manually.

The script doesn't handle either the namespace change described below.

Namespace change and MEDLoader high level API

The namespace ParaMEDMEM has been turned into MEDCoupling, and now contains MEDLoader high level API. The MEDLoader high level API is hence accessible:

  • at the MEDCoupling namespace level in C++ (direct static functions, no more MEDLoader class)
  • at the MEDLoader module level in Python. Scripts using the high level API of the MEDLoader typically need to get read of all the occurences of "MEDLoader." in their code.

Note that on the Python side the module MEDLoader is still here, but doesn't containt the MEDLoader class anymore. As before it re-includes all of MEDCoupling classes, plus the low level MEDLoader classes (MEDFile* classes).

Name changes - Reference list

The following changes have been applied:

  • methods ending with a number (mergeNodes2, ...) have been made more explicit
  • search functions have been unified (they all begin with 'findId(s)')
  • plus some other various renames
