Constructor Detail

DataSignal

public DataSignal(java.lang.String key,
                  MessageService message)

Constructs an DataSignal object using the input parameter(s).

Parameters:

key - The signal key.

message - org.eclipse.soda.dk.message.service.MessageService

Method Detail

getParameter

public ParameterService getParameter()

Gets the ParameterService parameter property value.

Returns:

Results of the get parameter (ParameterService) value.

messageReceived

public void messageReceived(TransportService transportService,
                            java.lang.Object timestamp,
                            MessageService message)

This API will be called each time the TransportService receives a valid message. Since other notifications are blocked until this method returns, implementors of this method should:

• Not cause the device or transport to be blocked (eg calling read on a measuremnt).
• Handle this call quickly and return.

Specified by:

messageReceived in interface MessageListener

Overrides:

messageReceived in class MessageSignal

Parameters:

transportService - The transport that received the message.

timestamp - The timestamp when the message was detected.

message - The message received.
