Field Detail

bmlRequestSender

private eu.semaine.jms.sender.XMLSender bmlRequestSender

fbManager

private BMLFeedbackManager fbManager

bmlRequestQ

private ConcurrentLinkedQueue<String> bmlRequestQ

Incoming BML Requests from the application are stored here. The main networking loop will get these requests and send them to the server if a connection is available.

feedbackLock

private Object feedbackLock

Locking object for the feedbacklisteners -- needed to avoid a situation where feedback is sent out simultaneously with setting the feedbacklisteners.

Throws:

javax.jms.JMSException

Method Detail

react

protected void react(eu.semaine.jms.message.SEMAINEMessage m)
              throws eu.semaine.exceptions.MessageFormatException

the message will be bml feedback... so send it on to any listeners

Overrides:

react in class eu.semaine.components.Component

Throws:

eu.semaine.exceptions.MessageFormatException

act

protected void act()
            throws javax.jms.JMSException

send next requests from bml request queue

Overrides:

act in class eu.semaine.components.Component

Throws:

javax.jms.JMSException

performBML

public void performBML(String bmlString)

performBML in interface RealizerBridge

addListeners

public void addListeners(BMLListener... bmlListeners)

Listeners must be stored; they will get updates from the feedbackRedirectionThread

Specified by:

addListeners in interface RealizerBridge
