      end - the optional end timestamp of the document's validity
      metadata - optional metadata to associate with the document
      Returns:
      a fully constructed SerializedDocument

      Returns:
      the target output type this converter produces

    • convert

      public Data<com.fasterxml.jackson.databind.JsonNode> convert(Data<byte[]> data)
      Description copied from interface: Converter
      Converts the given Data from input type I to output type O.
      Specified by:
      convert in interface Converter<byte[], com.fasterxml.jackson.databind.JsonNode>
      Parameters:
      data - the input data
      Returns:
      the converted data

    • convertFormat

      public Data<?> convertFormat(Data<byte[]> data)
      Description copied from interface: Converter
      Optionally converts the structure or format (e.g.: application/json) of the input data without modifying its core content.

      This method is used in scenarios where only a format change is required (e.g., wrapping metadata differently), and may return the original input or a modified version depending on the implementation.

      Specified by:
      convertFormat in interface Converter<byte[], com.fasterxml.jackson.databind.JsonNode>
      Parameters:
      data - the input data
      Returns:
      the format-converted data, or the original input (default implementation)
