    • fullBufferArray

      byte[] fullBufferArray() throws IOException
      Returns the full buffer array allowing an alternative protobuf parser to be used in marshallers, and at the root message level. This should not be mixed with the other tag reader read***() methods, or else an IllegalStateException will be thrown. Therefore you cannot mix protostream annotated models with other parsers reading the raw payload array.
      Throws:
      IOException

    • fullBufferInputStream

      InputStream fullBufferInputStream() throws IOException
      Returns the input stream allowing an alternative protobuf parser to be used in marshallers, and at the root message level. This should not be mixed with the other tag reader read***() methods, or else an IllegalStateException will be thrown. Therefore you cannot mix protostream annotated models with other parsers reading the raw payload input stream.
      Throws:
      IOException

    • isInputStream

      boolean isInputStream()
      Returns:
      Returns true if the original payload is InputStream based.
