45 * This file was created in order to respond to requirement of bug PAL10494:
46 * SMESH python dump uses idl interface.
48 * The creation reason is that smesh.py commands defining hypotheses encapsulate
49 * several SMESH engine method calls. As well, the dependencies between smesh.py
50 * classes differ from ones between corresponding SMESH IDL interfaces.
52 * Everything here is for internal usage by SMESH_2smeshpy::ConvertScript()
53 * declared in SMESH_PythonDump.hxx
55 * See comments to _pyHypothesis class to know how to assure convertion of a new
