Canonical term for something that can only occur once? Something that can occur multiple times?

Question

I'm really anal about what I name my classes, and I need an adjective for both something that is only allowed to happen once, as well as something that is allowed to happen multiple times.

examples:

• wordthatmeansitcanonlyhappenonceTrigger
• wordthatmeansitcanhappenmultipletimesTrigger

Answer 1

I usually use 'OneTime' for the single shot, and nothing particular for the multiple case. It's not really canonical though...

Answer 2

onceTrigger, manyTrigger

oneTrigger, manyTrigger

Also, sometimes I just don't name one (once or many) and name the other (once or many) to make it stand out. Maybe you could just put an 's' on the end of one and not the other.

Answer 3

I just use "OneTime." Maybe it's a poker thing.

Answer 4

OneShotTrigger
RepeatableTrigger

Answer 5

OneShotTrigger and RecurringTrigger

Answer 6

How about

• SingularTrigger
• PluralTrigger

Also, I don't think this is exactly what you're getting at, but this may be related to Idempotence.

Answer 7

For one time: nonce.

Answer 8

You could call them WyclefJeanTrigger and TimMcGrawTrigger. ;-)

With tongue ever so slightly in cheek, how about:

• BirthTrigger - you only get born once.
• BirthdayTrigger - but you can have lots of birthdays
