What you want is set-validator! :test can be used to store a unit test (typically for a function) but you should use clojure.test for writing unit tests, just ignore :test Usage: (set-validator! iref validator-fn) Sets the validator-fn for a var/ref/agent/atom. validator-fn must be nil or a side-effect-free fn of one argument, which will be passed the intended new state on any state change. If the new state is unacceptable, the validator-fn should return false or throw an exception. If the current state (root value if var) is not acceptable to the new validator, an exception will be thrown and the validator will not be changed. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
