Mother class modification propagation

# 9 years ago
lgluck	Hello, I would like to know how is propagated modifications done in mother class in the child class; I explain: I do a mother class implementating a state diagram for my application. All my device classes will inherit this mother class. If I update the mother class, for example - adding a state - or modififying a state transition is this/these modifications propagated to my child classes? If no, this means, that I have to update manually? If yes, is it done automatically, or by regenerating the device class … What is the procedure? Thanks by advance, Laurence.

Hello,

I would like to know how is propagated modifications done in mother class in the child class; I explain:

I do a mother class implementating a state diagram for my application. All my device classes will inherit this mother class.
If I update the mother class, for example
- adding a state
- or modififying a state transition
is this/these modifications propagated to my child classes?

If no, this means, that I have to update manually?
If yes, is it done automatically, or by regenerating the device class …
What is the procedure?

Thanks by advance,
Laurence.

Andy	Bonjour Laurence, sorry for the delay in answering. When you say Mother class do you mean a Tango device class? How do you do the inheritance? Do you use Pogo? Pogo lets you choose which commands and attributes to inherit. At least I think so. I let the Pogo expert(s) correct me if I am wrong. More answers to follow. Andy

lgluck	Bonjour Andy, thanks for the answer. - Yes, I mean a Tango device class when I was speaking about Mother class. - I do the inheritance using Pogo ("Add Inheritance Class" button). As far as I know I don't choose which attribute and command to inherit; I inherit of all: the inherited command and attributes can be seen with the different colors (and after I use it or not) - I don't know if the question was clear so I put it again: if in my mother class, I make some modifications, for example add/remove command/attribute, renaming of command/attribute … do that changes propagated in the child class WITHOUT manual intervention, by regenerating the code files and/or xmi file (menu File/Generate in Pogo) or should I do it manually as many time I have child classes which inherit of this updated mother class. Thanks, Laurence.

Pascal	Hi Laurence Normally if you modify the super class, if you reload your class with Pogo, the modifications will be taken in account. I cannot confirm for all cases of change, but it must be OK. If it is not, tell me what is wrong. Pascal
