      public class DirContentSource
      extends ContentSource

  A `ContentSource` using the Dir collection for its input. Supports the following configuration parameters (on top of `ContentSource`):
  - work.dir - specifies the working directory. Required if "docs.dir" denotes a relative path (default=work).
  - docs.dir - specifies the directory the Dir collection. Can be set to a relative path if "work.dir" is also specified (default=dir-out).

    - #### close

          public void close()
                     throws IOException

      Description copied from class: `ContentItemsSource`
      Called when reading from this content source is no longer required.
      Specified by:
        `close` in interface `Closeable`
      Specified by:
        `close` in interface `AutoCloseable`
      Specified by:
        `close` in class `ContentItemsSource`
      Throws:
        `IOException`

    - #### getNextDocData

          public DocData getNextDocData(DocData docData)
                                 throws NoMoreDataException,
                                        IOException

      Description copied from class: `ContentSource`
      Returns the next `DocData` from the content source. Implementations must account for multi-threading, as multiple threads can call this method simultaneously.
      Specified by:
        `getNextDocData` in class `ContentSource`
      Throws:
        `NoMoreDataException`
        `IOException`

    - #### resetInputs

          public void resetInputs()
                           throws IOException

      Description copied from class: `ContentItemsSource`
      Resets the input for this content source, so that the test would behave as if it was just started, input-wise.

      NOTE: the default implementation resets the number of bytes and items generated since the last reset, so it's important to call super.resetInputs in case you override this method.

      Overrides:
        `resetInputs` in class `ContentItemsSource`
      Throws:
        `IOException`

    - #### setConfig

          public void setConfig(Config config)

      Description copied from class: `ContentItemsSource`
      Sets the `Config` for this content source. If you override this method, you must call super.setConfig.
      Overrides:
        `setConfig` in class `ContentItemsSource`
