    Executes an operation once and -- when it fails with an exception -- retries it several times until no exception is thrown or the specified number of retries is exceeded.

    Executes an operation once and -- when it fails with an exception -- retries it several times until no exception is thrown or the specified number of retries is exceeded.

    n

    maximum number of retries

    delayMs

    milliseconds to wait between retries (non-negative value, defaults to 0)

    doIt

    operation to be executed

    returns

    the result of the last try of the operation in case of success

    Annotations
    @tailrec()
    Exceptions thrown

    Exception whatever is thrown by the last try of the operation in case of no success

    IllegalArgumentException if the value of delayMs is negative

    Note

    The maximum number of executions is equal to the maximum number of retries plus 1.
