                   int _device)
            throws java.io.IOException,

                   DatabaseCorruptException,
                   DatabaseDoesNotExistException

Creates a database given a path and a device. This assumes that the database is already created. Called on normal startup.

Method Detail

loadExistingDatabase

private void loadExistingDatabase()
                           throws java.io.IOException,
                                  DatabaseDoesNotExistException

This function loads an existing database from disk. First it sees if a correct path was specified. Throws some exceptions if things don't look correct. Assuming everything is OK, then an AdvAudioDB object is created. Eventually we need to add HiSi DB's and PC Audio DB.

Throws:

java.io.IOException

DatabaseDoesNotExistException

public void createEmptyDatabase()
                         throws java.io.FileNotFoundException,

Parameters:
