Re: [platform-debug-dev] IThread.getPriority() returns int. Not all platforms use int to represent

I believe that a debug model for a debug engine that is currently returning Strings, could provide an implementation that returns an int. It would require that you define ints for your appropriate Strings. Returning an internationalized String, at the model level (i.e. non-ui) does not feel right, as it requires clients of the model that depend on thread priorities to be able to handle internationalized strings (which is messy - i.e. how could one properly test the value of a thread priority to take some action? You would have to have an if statement that checks all the different internationalized values). The only good use for these Strings would be for presentation, which is not what the debug model is intended to do. I would prefer to see you extend the debug model if you need to return the Strings, with a method like #getThreadPriorityLabel(). However, I do not feel that should be part of the core debug model.

I would have to do a poll of the 10+ engines that we connect to but because
our plugin works with many different platforms we recently changed our
internal representation to a string allowing the engines to use numeric
values or terms like "Critical" or "Batch" for priorties.   We don't do
anything with the values other than display so a string works well.

The plugin that I am creating connects to debug engines on various
platforms.   Not all of them necessarily represent a thread's priority with
a number.

/**
* Returns the priority of this thread. The meaning of this
* number is operating-system dependent.
*
* @return thread priority
* @exception DebugException if this method fails.  Reasons include:
* <ul><li>Failure communicating with the VM.  The DebugException's
* status code contains the underlying exception responsible for
* the failure.</li>
*/
public int getPriority() throws DebugException;

Could IThread.getPriority() return a String instead?

I'm curious, which platform(s?) returns non-numeric thread priorities? What

does it(they?) use?
