discover

public abstract boolean discover(int _timeoutMillis)
                          throws java.io.IOException

Implemented by subclasses. This will actually perform the subclass-dependent mechanism of finding an Empeg (within the given timeout time)

---

fireEmpegDiscovered

protected void fireEmpegDiscovered(org.jempeg.empeg.protocol.event.EmpegDiscovererEvent _event)

Fires the EmpegDiscoered event

---

fireEmpegDiscovered

protected void fireEmpegDiscovered(EmpegDescription _description,
                                   ConnectionIfc _conn)

Fires the empegDiscovered event with the given description and connection.

---

getEmpegName

protected java.lang.String getEmpegName(ConnectionIfc _conn)
                                 throws java.io.IOException

Retrieves the name of the Empeg using the given connection (this uses getPlayerConfiguration of the ProtocolClient.

---

getPlayerType

protected java.lang.String getPlayerType(ConnectionIfc _conn)
                                  throws java.io.IOException

Retrieves the type of the Empeg using the given connection.

---

isEmpegConnected

protected boolean isEmpegConnected(ConnectionIfc _conn)
                            throws java.io.IOException
