  • Method Details

    • writeContent

      public final void writeContent(JsonWriter out) throws IOException
      Description copied from interface: DataObject
      Writes a JSON object containing keys for all fields of this object.

      In contrast to DataObject.writeTo(JsonWriter), the resulting object contains no type information. Therefore, this method must only be called directly, if the reader knows the type of the object to read from the context. For reading the data, a per-type generated read[type-name]() method must be called.

      Specified by:
      writeContent in interface DataObject
      Parameters:
      out - The writer to write to.
      Throws:
      IOException

    • writeFields

      protected void writeFields(JsonWriter out) throws IOException
      Writes all fields of this instance to the given output.
      Parameters:
      out - The writer to write to.
      Throws:
      IOException - If writing fails.

      public final void readContent(JsonReader in) throws IOException
      Description copied from interface: DataObject
      Reads a JSON object containing keys for all fields of this object.

      This method does not consider type information contained in the stream.
