Updated by Jules Waldhart about 8 years ago
I rebased it upon current version of planner bf2db3f6 (with conflicts) and studio (no issue)
I put the resulting commits on:
git://redmine.laas.fr/laas/users/jwaldart/perso-move3d/planners.git branch pullreq-state.

It seems to work, the modification is quite hazardous, but seems coherent. I was afraid that there was a link btw some Configuration and double* in p3d, but I couldn't find any.
- The pull-request lacks code documentation esp. in cont_state.
- class names shall be in CamelCase.
- all should be writen in english (attribute _Etat in Robot_state)
- I'm not sure about the necessity to have a separated cont_state: won't be used somewhere else, and could even introduce confusion. To be discussed.
Good job otherwise!
But not yet a +1...

- Status changed from New to In Progress
conditional +1
I detected a few inconsistencies that could be harmful in the future, in RobotState:- convertToRadian : needs to convert also the derivatives
- getConfigInDegree : idem
- operator= copies only the double* (configuration)
- operator==, != and equal() and: compares only the configuration.
- sub, add, mult idem (maybe unused -> delete them, or at least deprecate [1])
Also there is a bug:
There are cases where calling getConfigStruct causes segfault, probably because the state is not initialized. You need to test this in the method and return NULL.
--
Other future changes that could be needed: provide overloads to access to the nth derivative in each method that access to the configuration (double getActiveDof(uint), getEigenVector(), at(), operators () and [], ...
--
If the pull-request is urgent, can be accepted with just the bug correction, with issuing an high priority Bug including all this.
--
Also, a note for the future, think about putting re-factors in a separate commit, for readability (it's boring to have to sort real changes vs. re-factor changes when reading a commit)

footnotes
[1]: they are used only in HRICS_CF_TimeToCollision, which is dummy and can be modified (a reason why we need kinodyn motion planing :) )

here are my comments:
- The git tree is not very clean: adding and removing file in the same pull request might not be the best idea (note: it is ok for this time but let's try to keep it as clean as possible)
- SetConfiguration in RobotState: it is not setting anymore the libmove3d struct, it might introduce errors in the currently used algorithms.
- dist() in RobotState: specify the kind of distance computed: might be needed later.
- Concerning all the commented functions in RobotState: it is maybe not used right now, but I think these functions should be restaured
- the commit configuration.cpp/hpp refactor rename with a capital at the begining.
studio:
same coment concerning the git tree.

forgot to say I changed stuff wrt. the original pull-request (mainly to remove occurrences of Cont_state and Robot_state in the history):
in planners: squashed all the commits into one.
in studio: rewrite history, and moved some #includes from .h to .cpp (adding required forward declarations in .h)
