46 * This file was created in order to respond to requirement of bug PAL10494:
47 * SMESH python dump uses idl interface.
49 * The creation reason is that smesh.py commands defining hypotheses encapsulate
50 * several SMESH engine method calls. As well, the dependencies between smesh.py
51 * classes differ from ones between corresponding SMESH IDL interfaces.
53 * Everything here is for internal usage by SMESH_2smeshpy::ConvertScript()
54 * declared in SMESH_PythonDump.hxx
