Class ScreenShareSession

java.lang.Object

org.jivesoftware.smackx.jingle.media.JingleMediaSession

org.jivesoftware.smackx.jingle.mediaimpl.sshare.ScreenShareSession

public class ScreenShareSession
extends JingleMediaSession

This Class implements a complete JingleMediaSession. It sould be used to transmit and receive captured images from the Display. This Class should be automaticly controlled by JingleSession. For better NAT Traversal support this implementation don't support only receive or only transmit. To receive you MUST transmit. So the only implemented and functionally methods are startTransmit() and stopTransmit()

Constructor Detail

ScreenShareSession

public ScreenShareSession(PayloadType payloadType,
                  TransportCandidate remote,
                  TransportCandidate local,
                  String locator,
                  JingleSession jingleSession)

Creates a org.jivesoftware.jingleaudio.jmf.AudioMediaSession with defined payload type, remote and local candidates

Parameters:

payloadType - Payload of the jmf

remote - the remote information. The candidate that the jmf will be sent to.

local - the local information. The candidate that will receive the jmf

locator - media locator

Method Detail

initialize

public void initialize()

Initialize the screen share channels.

Specified by:

initialize in class JingleMediaSession

startTrasmit

public void startTrasmit()

Starts transmission and for NAT Traversal reasons start receiving also.

Specified by:

startTrasmit in class JingleMediaSession

setTrasmit

public void setTrasmit(boolean active)

Set transmit activity. If the active is true, the instance should trasmit. If it is set to false, the instance should pause transmit.

Specified by:

setTrasmit in class JingleMediaSession

Parameters:

active - active state

startReceive

public void startReceive()

For NAT Reasons this method does nothing. Use startTransmit() to start transmit and receive jmf

Specified by:

startReceive in class JingleMediaSession

stopTrasmit

public void stopTrasmit()

Stops transmission and for NAT Traversal reasons stop receiving also.

Specified by:

stopTrasmit in class JingleMediaSession

stopReceive

public void stopReceive()

For NAT Reasons this method does nothing. Use startTransmit() to start transmit and receive jmf

Specified by:

stopReceive in class JingleMediaSession

getFreePort

protected int getFreePort()

Obtain a free port we can use.

Returns:

A free port number.

setEncoder

public void setEncoder(ImageEncoder encoder)

setDecoder

public void setDecoder(ImageDecoder decoder)
