Constructor Detail

DataCommand

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

Constructs an DataCommand object using the key and messge parameters.

Parameters:

key - java.lang.String

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

Method Detail

execute

public void execute(java.lang.Object data)

Perform the execute action method.

Specified by:

execute in interface CommandService

Overrides:

execute in class SimpleMessageCommand

Parameters:

data - java.lang.Object

See Also:

CommandService.execute()

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 MessageCommand

Parameters:

transportService - The transport that received the message.

timestamp - The timestamp when the message was detected.

message - The message received.
