Non-reentrant C# timer
- by Oak
I'm trying to invoke a method f() every t time, but if the previous invocation of f() has not finished yet, wait until it's finished.
I've read a bit about the available timers (this is a useful link) but couldn't find any good way of doing what I want, save for manually writing it all. Any help about how to achieve this will be appreciated, though I fear I might not be able to find a simple solution using timers.
To clarify, if x is one second, and f() runs the arbitrary durations I've written below, then:
Step Operation Time taken
1 wait 1s
2 f() 0.6s
3 wait 0.4s (because f already took 0.6 seconds)
4 f() 10s
5 wait 0s (we're late)
6 f() 0.3s
7 wait 0.7s (we can disregard the debt from step 4)
Notice that the nature of this timer is that f() will not need to be safe regarding re-entrance, and a thread pool of size 1 is enough here.
