I am developing a game with Action Script 3.0 using Starling Framework, converting it from C++

C++ Code :

for (std::vector<MyObject*>::iterator i = m_listEnemy->begin();i!= m_listEnemy->end();)
{

    (*i)->update(dt);
    if ( (*i)->m_Hp <=0 )
    {
            (*i)->release();
            i = m_listEnemy->erase(i);
            continue;
    }
    i++;
}

MyObject is the class.

What Action Script 3.0 data type matches the C++ iterator? Also , how can I convert this C++ code to Action Script 3.0 code? Thanks in advance!
