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?

Best,
