    Vector.<*> triggers a "Problem" in Flash Builder but doesn't create an error during runtime.

    DJ Gecko Level 1

      In Flash Builder 4.6 I get an error for this:

       

      var testVector:Vector.<*> = new Vector.<*>();

      trace(testVector.length);

       

      Sometimes the error shows up in the "Problems" panel and pointing at the trace it says something about byte code. Other times it just shows the "?" symbol next to the trace command that says "Access of undefined property length".

       

      When I test the movie there are no runtime errors.

       

      Can someone explain this?

       

      cheers.

          Why would you do that anyway?

           

          If the thing about vectors over arrays is there speed because they don't have to resolve datatypes, setting it to an untyped * seems a bit weird. You could use Vector.<Object> instead which is practically the same thing, but is at least a defined type so might eliminate the compiler warning.

           

          But, again, why do this?

           

          When I use Vector, it is because I want to do fast operations with a set of items of a known datatype or interface and, for that, Vector makes coding exceptionally easy and satisfying. But with a pretty much undefined type like * or Object, all of those advantages are lost as, at the very least, you have to do type checking interrogation whenever you want to process what you have.

            Hi Gaius,

             

            There are lots of reason why I would want to use a vector this way.

             

            One is for building a shuffle function that will shuffle any type of Vector.

             

            public function shuffleArray(array:Vector.<*>):void

                                {

                                          for (var i:int = array.length-1; i >=0; i--)

                                          {

                                                    var randomIndex:int = Math.floor(Math.random()*(i+1));

                                                    var itemAtIndex:Object = array[randomIndex];

                                                    array[randomIndex] = array[i];

                                                    array[i] = itemAtIndex;

                                          }

                                }

             

            var testVector:Vector = new Vector.<uint>( [1, 2, 3, 4] );

             

            shuffleArray(Vector.<*>(testVector));

             

            Changing it from * to Object did not work.

             

            Thanks.

              Very surprised if that doesn't work as vector.<Object>.

               

              I can see why that would be useful, but the same could be achieved with;

              [code]

              public static function randomSort(a:*,b:*):int { return Math.random()>0.5?1:-1; }

               

              var testVector:Vector.<uint> = Vector.<uint>([1,2,3,4]);

               

              testVector = testVector.sort(randomSort);

              [/code]

              (Plus there is the possibility of an invalid index with your sort function when random returns 1.)

                Hi Gaius,

                 

                When using a * or Object with a Vector the code does work, but Flash Builder shows the "?" mark error, and sometimes, for some strange reason, will show the "!" problem. Please read my original post.

                 

                The sort method for randomizing doesn't produce a very good result.

                 

                "...there isn’t an even 1/26 chance that any given letter will end up in any given slot. This is because we’re only swapping adjacent pairs of elements, and doing no more than that. Still, it’s a neat method..."

                 

                That quote is taken from here: http://active.tutsplus.com/tutorials/actionscript/quick-tip-how-to-randomly-shuffle-an-arr ay-in-as3/

                 

                cheers.

                  That's a good article, but my comment on invalid index still holds with what you have. One of his other approaches would avoid that.

                   

                  For the undefined property length, I think the compiler is struggling to deduce properties when it is expecting a defined type and is receiving instead *.

                   

                  Vector is intentionally specific about typing because that is one of the ways it makes its performance gains - it can run more efficiently when it doesn't need to interrogate each piece of data to deduce what it is etc.

                    This avoids the problem and means you can use the function with Array as well as with Vector.

                    [code]

                    protected static function randomSortArrayOrVector(a:Object):void {

                                                  if(a.hasOwnProperty('length')) {

                                                            var l:int = a['length'];

                                                            for (var i:int = l-1; i>-1; i--)

                                                            {

                                                                      var randomIndex:int = int(Math.random()*(l-1));

                                                                      var itemAtIndex:Object = a[randomIndex];

                                                                      a[randomIndex] = a[i];

                                                                      a[i] = itemAtIndex;

                                                            }

                                                  }

                    }

                      OK, I take that back, I read up on the docs and see that Math.random() returns 0 <= n < 1 where I thought it was <=1.

                       

                      I also ran a test bed on the Math.random() thing and I see what your man means. My method of calculating the index gave a slight imbalance towards the end of letter distributions, but I can't see why!

                       

                      Have reverted to yours for the below, on first run it looked good, but I am seeing a cluster around the original letter position? (EG: Follow position 0 for a, position 1 for b etc. and you will see they have a disproportionate number there.)

                        Huh.

                        Not happy with that, only managed to get an even distribution after

                        a) modifying the index selection to ensure there is

                        b) running the random sort twice

                        Otherwise, I was seeing a seemingly unavoidable cluster around the original position of the letter.

                              Hi,

                               

                              I didn't mean to start a discussion about approaches for shuffling an array. I just want to understand why the Vector.<*> and Vector.<Object> are giving errors in Flash Builder but running fine during run time and not giving any errors. I completely understand what an index array is for (Vector Array), but sometimes, as I demonstrated, I do need to use * or Object.

                               

                              Cheers.
