set-error-mode! (clj)

function

(set-error-mode! a mode-keyword)

Sets the error-mode of agent a to mode-keyword, which must be either :fail or :continue. If an action being run by the agent throws an exception or doesn't pass the validator fn, an error-handler may be called (see set-error-handler!), after which, if the mode is :continue, the agent will continue as if neither the action that caused the error nor the error itself ever happened. If the mode is :fail, the agent will become failed and will stop accepting new 'send' and 'send-off' actions, and any previously queued actions will be held until a 'restart-agent'. Deref will still work, returning the state of the agent before the error.
