configureDIOConnection

public void configureDIOConnection()
                            throws Exception

Throws:

Exception

onConnectionEstablished

public void onConnectionEstablished()

Description copied from interface: CloudClientListener

Called when the CloudClient has successfully connected with the broker.
If the bundle using the client relies on subscriptions beyond the default ones, it is responsibility of the application to implement the CloudClientListener.onConnectionEstablished() callback method to restore the subscriptions it needs after a connection loss.

Specified by:

onConnectionEstablished in interface CloudClientListener

onConnectionLost

public void onConnectionLost()

Description copied from interface: CloudClientListener

Called when the client has lost its connection with the broker. Depending on the DataService configuration, the client will attempt to reconnect and call the CloudClientListener.onConnectionEstablished() method upon a successful reconnect. This is only a notification, the callback handler should not attempt to handle the reconnect.
If the bundle using the client relies on subscriptions beyond the default ones, it is responsibility of the application to implement the CloudClientListener.onConnectionEstablished() callback method to restore the subscriptions it needs after a connection loss.

Specified by:

onConnectionLost in interface CloudClientListener

onControlMessageArrived

public void onControlMessageArrived(String deviceId,
                                    String appTopic,
                                    EsfPayload msg,
                                    int qos,
                                    boolean retain)

Description copied from interface: CloudClientListener

Called by the CloudClient when it receives a published control message from the broker. If the message received has a binary payload that it has NOT been encoded using the the EsfPayload class, the received bytes will be set as the body field of a new EsfPaylaod instance which is passed to the callback Listener interface.

Specified by:

onControlMessageArrived in interface CloudClientListener

Parameters:

deviceId - The deviceId this message was addressed to.

appTopic - The appTopic the message arrived on.

msg - The EsfPayload that arrived.

qos - The Quality of Service that the message was received on.

retain - Whether the message was retained by the broker.

onMessageArrived

public void onMessageArrived(String deviceId,
                             String appTopic,

                             int qos,
                             boolean retain)

Description copied from interface: CloudClientListener

Called by the client when it receives a published data message from the broker. If the message received has a binary payload that it has NOT been encoded using the the EsfPayload class, the received bytes will be set as the body field of a new EsfPaylaod instance which is passed to the callback Listener interface.

Specified by:

onMessageArrived in interface CloudClientListener

Parameters:

deviceId - The asset ID of the semanticTopic prefix the message arrived on.

appTopic - The appTopic the message arrived on.

msg - The EsfPayload that arrived.

qos - The Quality of Service that the message was received on.

retain - Whether the message was retained by the broker.

onMessagePublished

public void onMessagePublished(int messageId,
                               String appTopic)

Description copied from interface: CloudClientListener

Called by the CloudClient when a message has been transfered from the publishing queue to the underlying DataTransportService for publishing on the wire.

Specified by:

onMessagePublished in interface CloudClientListener

onMessageConfirmed

public void onMessageConfirmed(int messageId,
                               String appTopic)

Description copied from interface: CloudClientListener

Called by the CloudClient when a published message has been fully acknowledged by the broker, as appropriate for the quality of service. The published method is not called for QoS 0 publications.

Specified by:

onMessageConfirmed in interface CloudClientListener

Parameters:

messageId - The message id of the published message

isDIO_Changed

public boolean isDIO_Changed()

setDIO_Changed

public void setDIO_Changed(boolean dIO_Changed)
