It is possible to make private setter and public getter on actionscript classes. All you need is to use proper namespaces for getter and setter within the class.

package
{
    public class GSTest extends Object
    {
        private var _foo:String;

        public function GSTest()
        {
            super();

            // setting value
            private::foo = "bar";

            // getting value
            trace(public::foo);
        }

        public function get foo():String
        {
             return _foo;
        }

        private function set foo(value:String):void
        {
             _foo = value;
        }
    }
}

usage:

var gsTest:GSTest = new GSTest();
trace(gsTest.foo); // returns "bar"

compilation error:

var gsTest:GSTest = new GSTest();
gsTest.foo = "hallo";
