ThreadPoolExecutor.DiscardPolicy cannot be resolved

[Bai Shen]

I'm creating a ThreadPoolExecutor and trying to set the rejection handler. However, Eclipse keeps giving me the error that ThreadPoolExecutor.DiscardPolicy cannot be resolved, even though it autocompletes it.

Am I missing something? I can't figure out a reason that it shouldn't work.

How did you import it?

[Bai Shen]

The same way I do all of my imports. I let Eclipse autocomplete it.

This resulted in an import statement for ThreadPoolExecutor. I tried adding one for ThreadPoolExecutor.DiscardPolicy, but that didn't do anything.

I tried it in my Eclipse: I imported ThreadPoolExecutor and put in this line of code:

ThreadPoolExecutor.DiscardPolicy z = null;

Eclipse doesn't have a problem with that.

[Bai Shen]

Yeah, that worked for me too. But I never thought to try that. And I'm still not sure what it gets me. I was doing the following.

		ThreadPoolExecutor tpe = new ThreadPoolExecutor(1, 1, 0L, TimeUnit.MILLISECONDS, q, ThreadPoolExecutor.DiscardPolicy);

Where q is my queue.

That wouldn't work because you can't pass a type name as a parameter. You need an instance of ThreadPoolExecutor.DiscardPolicy in that position, don't you?

Apparently so. When I was originally coding it, I thought DiscardPolicy was just a flag for ThreadPoolExecutor. I didn't realize it was it's own object.
