  - ### Method Detail

    - #### getInputFileExtension

          public String getInputFileExtension()

      Description copied from interface: `SolutionFileIO`
      Every `PlanningSolution` type potentially has its own file extension. If no specific file extension is defined by the use case, the following are recommended:
      - If this `SolutionFileIO` implementation serializes to XML, use file extension "xml".
      - If this `SolutionFileIO` implementation serializes to text, use file extension "txt".
      - If this `SolutionFileIO` implementation serializes to binary, use file extension "dat".

      It's good practice that both the input and the output file have the same file extension, because a good output file is able to function as an input file. Therefore `SolutionFileIO.getOutputFileExtension()` defaults to returning the same as this method.

      The file extension does not include the dot that separates it from the base name.

      This method is thread-safe.

      Specified by:
        `getInputFileExtension` in interface `SolutionFileIO<Solution_>`
      Returns:
        never null, for example "xml"

    - #### read

          public Solution_ read(File inputSolutionFile)

      Description copied from interface: `SolutionFileIO`
      This method is thread-safe.
      Specified by:
        `read` in interface `SolutionFileIO<Solution_>`
      Parameters:
        `inputSolutionFile` - never null
      Returns:
        never null

    - #### write

          public void write(Solution_ solution,
                            File outputSolutionFile)

      Description copied from interface: `SolutionFileIO`
      This method is thread-safe.
      Specified by:
        `write` in interface `SolutionFileIO<Solution_>`
      Parameters:
        `solution` - never null
        `outputSolutionFile` - never null, parent directory already exists
