Constructor Detail

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 Detail

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.
