  • Method Detail

    • getReason

      public CannotProvideCoderException.ReasonCode getReason()

      Returns:

      the reason that Coder inference failed.

    • getRootCause

      public Throwable getRootCause()

      Returns the inner-most CannotProvideCoderException when they are deeply nested.

      For example, if a coder for List<KV<Integer, Whatsit>> cannot be provided because there is no known coder for Whatsit, the root cause of the exception should be a CannotProvideCoderException with details pertinent to Whatsit, suppressing the intermediate layers.
