      AxonConfigurationException - if the value asserts to false by the assertion

    • assertNonNull

      public static <T> void assertNonNull(T value, String exceptionMessage) throws AxonConfigurationException
      Assert that the given value is non null. If not, an AxonConfigurationException is thrown containing the provided exceptionMessage.
      Type Parameters:
      T - a generic specifying the type of the value, which is the input for the assertion
      Parameters:
      value - a T specifying the value to assert
      exceptionMessage - The message for the exception.
      Throws:
      AxonConfigurationException - if the value equals null

    • assertPositive

      public static void assertPositive(int i, String exceptionMessage)
      Assert that the given value is positive, meaning greater than, or equal to, zero. If not, an AxonConfigurationException is thrown containing the provided {code exceptionMessage}.

      Parameters:
      l - the value to assert
      exceptionMessage - the message for the exception

    • assertStrictPositive

      public static void assertStrictPositive(int i, String exceptionMessage)
      Assert that the given value is strictly positive, meaning greater than zero. If not, an AxonConfigurationException is thrown containing the provided {code exceptionMessage}.
      Parameters:
      i - the value to assert
      exceptionMessage - the message for the exception.

    • assertStrictPositive

      public static void assertStrictPositive(long l, String exceptionMessage)
