Constructor Detail

SystemAccess

public SystemAccess(PoddyFrame mainWin)

The standard constructor for this class, here the main window object is handed over from the application when creating this object

Parameters:

mainWin - the main window of the application

Method Detail

getCDDiscID

public String getCDDiscID()

This method retrieves CD ROM information and fetches a disc identifier string that can be used from CDDB to identify this disc

Returns:

the disc ID in format "DDDDDDDD t1 t2 t3 .. tn" where DDDDDDDD is the ID of the whole disc and the t1..tn contain position information of the different tracks

getDVDDiscID

public long getDVDDiscID()

This method retrieves DVD ROM information and fetches a disc identifier string that can be used from DVD databases to identify this disc

Returns:

the disc ID in format "DDDDDDDD"

isWorking

public boolean isWorking()

This method can be used to find out if there is currently an operation in progress: as long as a workCmd is active and handled by the run() method here true is returned

Returns:

true when a working command is processed by the run() method, false otherwise

setCDTrack

public boolean setCDTrack(int track,
                          String path,
