Question

I want merge 2 array collection, where no duplicates are allowed,

var ac1:ArrayCollection = new ArrayCollection([ {s:"4",e:"8"}, {s:"9",e:"10"}, ]);
var ac2:ArrayCollection = new ArrayCollection([ {s:"2",e:"3"}, {s:"4",e:"8"}, {s:"9",e:"10"}, {s:"11",e:"12"}, ]);

how can I do it in efficient way

Thanks,

Perhaps this is a good starter.

function equals(o1:Object, o2:Object)
{
    return (o1 && o2) && (o1 != o2) && (o1.s != o2.s) && (o1.e != o2.e);
}

function merge(a:Array, b:Array):Array
{
    const source = [];
    var isContained:Boolean = false;
    for (var i:int; i< a.length;i++) {
        isContained = false
        for (var j:int; j< b.length;j++) {
            if (equals(a[i], b[j])) {
                isContained = true;
                break;
            }
        }
        if (!isContained) {
            source.push(a[1]);
        }
    }
    return source.concat(b);
}
