Class Scanner

java.lang.Object
  org.qtunes.scanner.Scanner

All Implemented Interfaces:

java.lang.Runnable, Service

public class Scanner
extends java.lang.Object
implements Service, java.lang.Runnable

The Scanner scans the disk looking for new files, and attempts to load them by calling TrackReader.read(java.io.File). If it succeeds it adds the tracks to the database.

Constructor Summary

Scanner()

Method Summary

ServiceContext	getContext() Return the ServiceContext that was passed into Service.startService(org.qtunes.core.ServiceContext)
long	getLastScan() Return the timestamp of the last scan in milliseconds
java.io.File	getRoot() Return a list of paths this Scanner will traverse
java.util.Map<java.lang.String,java.lang.Object>	reportState() Return a Map describing the state of this Service, for serialization back to any client that needs to know (eg webplayer) - so values should be serializable objects, eg Lists, Maps or simple objects.
void	rescan() Rescan for any tracks changed since the last scan
void	rescan(long lastscan) Rescan for any tracks changed since the specified timestamp
void	run() The main scanning thread
void	startService(ServiceContext context) Start the Service
void	stopService(ServiceContext context) Stop the Service
