Polling best practices

[LordDawn]

I want to create an update method that is called 12 times per second, what would be the best practice for this?

Currently I'm using this for a 5 minute task, but is it still the best method for a 12 times per second task, or should I use a thread with a thread-sleep in it, or is there a better method still?

Code: Select all

      m_taskHandle = sfs.getTaskScheduler().scheduleAtFixedRate(new MyScheduler(), 0, 300, TimeUnit.SECONDS);


Many thanks.

Hi,
yes you can use a scheduler task set to 83 milliseconds (1000/12)

Cheers

Cool, thanks Lapo.

And it's still performant to use "new <class>" in the scheduleAtFixedRate, creating and destroying class instances that fast?

[Lapo]

There's no other way
Unless you want to pool and reuse objects, there's nothing inherently wrong with creating new objects relatively fast. (80 msec intervals are not that fast, a for loop is much faster ). Unless these objects have a very high cost of instantiation, in which case pooling might be a consideration.

But, again, generally speaking, it's just fine to use new

Cheers
