OperatorChain - execute subprocess line by line

radone

I have class OperatorChain which has two (extendable) inner ports:
- OutputPortExtender
- InputPortExtender
(see the figure below)

#######################
#                     #
##-------Line 1------##
#                     #
##-------Line 2------##
#                     #
#     ...             #
#                     #

Is it possible to execute process in a "line by line" manner (i.e. port by port)?

Currently I call:

getSubprocess(0).execute();

I would like to save processing time and execute next "lines" only if the previous lines go well (something like AdaBoost).

The only possible way I know is to terminate the execution by throwing an exception in the inner operator. I am afraid that capturing exceptions can be much slower.

Thanks for any help.

Hi,

it seems like your "lines" are independent. Can't you make multiple subprocess and put a "line" into each?

The problem is, I expect the number of subprocesses would be approx. 40 (and might be even more).
In case of subprocesses it should work, however the GUI interface will be quite .
If the same would be possible in line by line approach it would be much better.

Hi,

just to make sure we are talking about the same thing: These 40 subprocess you are expecting, are all different, so the user has to do a lot of process design work anyway, right?

I expect these processes will be designed by genetic programming*, therefore it wont be much time.

* I hope I will find some time to to contribute to RCOMM this year and present our work.

Hi,

that sounds cool! But if the process is designed by GP, it should not be a big problem that it clutters up the design perspective - after all the user will not really look at it, so you can go with 40 subprocesses. That sounds like the most reasonable idea to me.
