  - ### QNModelReader

    public QNModelReader(DataReader dataReader)
    Initializes a `QNModelReader` via a `DataReader`.
    Parameters:
      `dataReader` - The `DataReader` that references the model to be read.

  - ### QNModelReader

    public QNModelReader(File file) throws IOException
    Initializes a `QNModelReader` via a `File`.
    Parameters:
      `file` - The `File` that references the model to be read.
    Throws:
      `IOException` - Thrown if IO errors occurred.

- ## Method Details

  - ### checkModelType

    public void checkModelType() throws IOException
    Description copied from class: `AbstractModelReader`
    Checks the model type via the the underlying `DataReader`.
    Overrides:
      `checkModelType` in class `GISModelReader`
    Throws:
      `IOException` - Thrown if IO errors occurred checking the model type.

  - ### constructModel

    public QNModel constructModel() throws IOException
    Retrieves a model from disk.

    If you are creating a reader for a format which won't work with this (perhaps a database or xml file), override this method and ignore the other methods provided in this abstract class.

    Overrides:
      `constructModel` in class `GISModelReader`
    Returns:
      The `QNModel` stored in the format and location specified to this `QNModelReader` (usually via its constructor).
    Throws:
      `IOException` - Thrown if IO errors occurred during (re-)construction.
