39 * \brief Tool converting SMESH engine calls into commands defined in smesh.py
41 * This file was created in order to respond to requirement of bug PAL10494:
42 * SMESH python dump uses idl interface.
44 * The creation reason is that smesh.py commands defining hypotheses encapsulate
45 * several SMESH engine method calls. As well, the dependencies between smesh.py
46 * classes differ from ones between SMESH IDL interfaces.
48 * The only API method here is SMESH_2smeshpy::ConvertScript(), the rest ones are
51 * See comments to _pyHypothesis class to know how to assure convertion of a new hypothesis

246 * \brief Root class for hypothesis
248 * HOWTO assure convertion of a new hypothesis
249 * In NewHypothesis():
250 * 1. add a case for the name of the new hypothesis and
251 * 2. initialize _pyHypothesis fields:
252 * . myDim - hypothesis dimention;
253 * . myType - type name of the algorithm creating the hypothesis;
254 * . myCreationMethod - method name of the algorithm creating the hypothesis;
255 * . append to myArgMethods interface methods setting param values in the
256 * order they are used when myCreationMethod is called. It is supposed that
257 * each interface method sets only one parameter, if it is not so, you are
258 * to derive a specific class from _pyHypothesis that would redefine Process(),
259 * see _pyComplexParamHypo for example
