No Duplicates or Not Adding Items to an ArrayCollection if the item already exists

November 21, 2009

This is a very clean and nifty way to make sure no same Object is in the ArrayCollection.

var myAC:ArrayCollection = new ArrayCollection();
    myAC.addItem(someObject);
// check if it is already in the ArrayCollection
if (!myAC.contains(someObject)) {
      // not included
      myAC.addItem(someObject)
}
