Design Pattern: Recursive Timers

[rlkoshak (Rich Koshak)]

This DP is very old and due for a rewrite. There are better approaches (see Design Pattern: Cascading Timers and Design Pattern: Looping Timers). I would not recommend using this DP any longer, at least until I can rewrite it which will take a bit.

1. That is correct, it should be createDoorTimer
2. I’ll take your word for it. I don’t see it but have no doubt it is missing.
3. I don’t remember any longer. Maybe. At one time I was storing the lambda itself in the map but that doesn’t seem to make sense here.
4. Yes, same typo. At some point I decided on a new name (probably last time I edited the Rule) and wasn’t consistent.

I’m picking up your timer example (instead of the Expire-Binding) because I’m trying to create an recursive timer with prolonged duration (first iteration time x, second 2x, third 3x…) - but for the time being I have no luck. Does someone have an idea what the problem is / a way to debug this code?

Use Looping timers as I linked above. That will be a better approach I think.

EDIT: Ok, found my mistake: I tried to call the function above from inside of another lambda function. Seems like that doesn’t work.

Global vars and vals cannot see each other. If you have a lambda that needs to call another lambda, you must pass it as an argument.
