    - #### withGenerator

          public JsonGenerationException withGenerator(JsonGenerator g)

      Fluent method that may be used to assign originating `JsonGenerator`, to be accessed using `getProcessor()`.
      Parameters:
        `g` - Generator to assign
      Returns:
        This exception instance (to allow call chaining)

        2.7

    - #### getProcessor

          public JsonGenerator getProcessor()

      Description copied from class: `JsonProcessingException`
      Method that allows accessing underlying processor that triggered this exception; typically either `JsonParser` or `JsonGenerator` for exceptions that originate from streaming API. Note that it is possible that `null` may be returned if code throwing exception either has no access to processor; or has not been retrofitted to set it; this means that caller needs to take care to check for nulls. Subtypes override this method with co-variant return type, for more type-safe access.
      Overrides:
        `getProcessor` in class `JsonProcessingException`
      Returns:
        Originating processor, if available; null if not.
