Or even shorter:
public function handleUpdate(a:Object,b:Object,c:Object,d:Object)
{
var handlerName:String = 'onUpdate';
if (a.selected){handlerName+= 'A'};
if (b.selected){handlerName+='B'};
// etc.
if (this[handlerName]==undefined)
{
trace("We haven't got a handler called:"+handlerName);
return;
}
this[handlerName]();
}
public function onUpdateA()
{
// do stuff for A etc.
}
public function onUpdateAB()
{
// do stuff for AB etc.
}
