如果Adobe Air ANE影响或与Adobe Air发生冲突

Question

Because Adobe Air ANE enable developer to write native codes to control almost everything. So I wonder if it is possible ANE codes influence or conflict with Adobe Air native functions. For example, I turn the volume by actionscript3. meanwhile, I also adjust volume by ANE. Is it possible causes error or conflicts?

Answer 1

AS3 is single threaded and completely linear. Two things cannot happen at the same time, even with an ANE (unless you use the ANE to leverage a second thread, obviously). Basically, with an ANE, you call a method from a SWC/AS3 library that calls a method in native code. The native code runs and then comes back to the SWC/AS3 library and then back to the originating code.

So...

as3 -> start changeVolume()
as3 library -> start changeVolume()
native code -> changeVolume()
as3 library -> finish changeVolume()
as3 -> finish changeVolum()
as3 -> next set of instructions run

EDIT: I should mention that this is not entirely true anymore. You can use workers that will allow you to utilize other threads. However, the most likely case for an ANE is on mobile and the workers do not currently work for mobile devices.

Answer 2

As I know, ANE just works like an library in AS3 code. It works like a linked SWC. So you just treat ANE as a SWC as a part of AS3 library code and wouldn't worry conflicts.
