time management between objects

[tinnitus]

hello,

I notice a behavior with class containing wait fonction i don't expect

ie: i have to objects child of the same parent , both contain a wait ( simulating a wait for a device to respond  for exemple)

when putting calcul one after other it is normale to add times

but when both object are distinct i don't understand why times are added too ...

that let think that pause fonction are dependants ...

here a vi to test , the good one is "test para 2"

Best regards

Make it reentrant?

Hello,

yes it works but i don't understand why they share a common timer without make it reentrant ...

do you mean its a normal behavior ?

may be i have to create a timer object ?

In fact it works for the little example but not in the big project where class1 is an element of other class ...

The behaviour I described for non-re-entrant VIs I posted in my Action Engine Nugget still apply in LVOOP.

So I would say this is expected behaviour.

Hello Ben,

Thanks for the link,

The idea is the same except that AE is unique, with class we can have severals instances

but idea is the same

I agree with the property of non reentrant function and that a functionality i would preserve.( preventing race condition)

and making calc method reentrant break that ( the alocation of  different memory space is not enable with class method )

so two calc are done in 100ms with two differents object  but if i connect the same object twice in the loop this time while expecting a 200ms 

(due to the protection ) it takes 100ms and that is not safe even if coding such a thing could not exist

To simplify

when 5 persons  run together during 10min the trainy take 10min                        // parallel tasks

if they  run a relay the total must be 50 min                                                       // serial tasks

and if we ask a person is to run  5 times 10 min he cannot do it in 10 min            // parrallel tasks serialized due to protection

Is there a way to obtain that

i will perform others tests tomorow ...
