GISModelReader

public GISModelReader(File file)
               throws IOException

Initializes a GISModelReader via a File.

Parameter:

file - The File that references the model to be read.

Löst aus:

IOException - Thrown if IO errors occurred.

GISModelReader

public GISModelReader(DataReader dataReader)

Initializes a GISModelReader via a DataReader.

Parameter:

dataReader - The DataReader that references the model to be read.

Methodendetails

constructModel

public AbstractModel 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.

Angegeben von:

constructModel in Klasse AbstractModelReader

Gibt zurück:
