- Drop variable current_external_state_
- Instead encode the info that the external state wasn't yet forwarded to any child via stage = children().cend()
- If all children have exhausted their solutions for this state, it is removed from the pending list
Setting up a demo for
Fallbacks({CartesianPath,PTP,RRTConnect})
I found the logic did not work as expected yet.
- process last job spec as well
- ignore failures when looking for a solution
- add more debug output
Note that while this ensures other stages outside the Fallbacks container
can compute as well, it does not solve the problem internally.
A new incoming state will only ever be considered once
the current stage cannot compute any more.
We have no way of telling a child to compute for *a specific state* for now.
So once we copied a state to its interface we have to let it compute until
all possibilities are exhausted to detect whether or not it could generate a solution for it.
If we wouldn't do so, there were no way of knowing when to fall back
to the next child as long as the stage can still compute on *any* copied solution.
Keep the previous logic around for Generator stages.
Note that this only makes sense for *pure* Generators and not for MonitoringGenerator,
because for the latter we would expect monitored solutions to be passed individually
(similar to pruning).
This could have been done already back when `runCompute` was introduced.
Wrapping the calls in try/catch comes from the previous implementation directly
calling `compute()`.
... in favor of checking version numbers.
Checking for one header was used for multiple independent things.
In theory we could do exact feature testing instead of using the next release number,
but in practice nobody cares about the individual commits between older releases.
Implement visualization as red-green arrow
* overload makeArrow to allow creation with points
* create new function for visualization
* if no plan is found, construct arrow from green cylinder and red arrow
* adjust arrow construction for backward propagators
Get hashing for inverted lookups, but incur
structural overhead.
Whether this is worth it depends on the number of mapped interface states
and the number of pruning/reactivation requests.
