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