[flexcoders] Re: Extend Array

[Tim Hoff]

Yep, thought that I could get away with not testing it.  Doesn't look
like you can extend Array, but you can extend ArrayCollection:

package
{
      import mx.collections.ArrayCollection;

      public class MatRix extends ArrayCollection
      {
           public function MatRix(numRows:int=0,numCols:int=0)
           {
                 for (var i:int=0;i<numRows;i++)
                {
                     this.addItem( new Array(numCols) );
                }
           }
      }
}

Test:

var a:MatRix = new MatRix(3,3);
a[0][1] = "test";
trace(a[0][1]);
