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.
- Specified by:
constructModelin classAbstractModelReader- Returns:
- The
GISModelstored in the format and location specified to thisGISModelReader(usually via its constructor). - Throws:
IOException- Thrown if IO errors occurred during (re-)construction.
-
checkModelType
public void checkModelType() throws IOExceptionDescription copied from class:AbstractModelReaderChecks the model type via the the underlyingDataReader.- Specified by:
checkModelTypein classAbstractModelReader- Throws:
IOException- Thrown if IO errors occurred checking the model type.
