Two good points.
I used an Array, as I wrote, to try to show how Jason might have done what he
had initially intended using arrays. I didn't mean to suggest that that's how
it would be best done. Sorry for confusion. I guess I just like the similarity
of arrays and objects - something that is not seen in all languages.
As for efficiency, I would probably go with static const int's (in lieu of
enums) and use an array. This would require to iterating - just simple offset
into array. Something like,
static const PAYMENT_TYPE_AC:int = 0;
static const PAYMENT_TYPE_RN:int = 1;
static const PAYMENT_TYPE_CP:int = 2;
static const PAYMENT_TYPE_CR:int = 3;
static const PAYMENT_MESSAGES:Array =
[
"Remember to reset the station
address.",
"Remember to reset the station
expiration date.",
"Remember to contact contractor to
remove the certificates from this station.",
"Remember to cancel the refund payment."
];
If there are better ways, I am always happy to hear them. I am still pretty new
to this Flex thing.
