Class MPDStandAloneMonitor

java.lang.Object
  org.bff.javampd.monitor.MPDEventMonitor
      org.bff.javampd.monitor.MPDStandAloneMonitor

All Implemented Interfaces:

java.lang.Runnable

public class MPDStandAloneMonitor
extends MPDEventMonitor
implements java.lang.Runnable

MPDStandAloneMonitor monitors a MPD connection by querying the status and statistics of the MPD server at given delay intervals. As statistics change appropriate events are fired indicating these changes. If more detailed events are desired attach listeners to the different controllers of a connection or use the MPDEventRelayer class.

Nested Class Summary

static class

MPDStandAloneMonitor.PlayerStatus The status of the player.

Constructor Summary

MPDStandAloneMonitor(MPD mpd)
Creates a new instance of MPDStandAloneMonitor using the default delay of 1 second.

MPDStandAloneMonitor(MPD mpd, int delay)
Creates a new instance of MPDStandAloneMonitor using the given delay interval for queries.
