Constructor Detail

SignalListeners

public SignalListeners(SignalListener[] objects)

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

Parameters:

objects - org.eclipse.soda.dk.signal.service.SignalListener[]

See Also:

SignalListeners(SignalListener,SignalListener)

SignalListeners

public SignalListeners(SignalListener currentObject,
                       SignalListener newObject)

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

Parameters:

currentObject - SignalListener

newObject - SignalListener

See Also:

SignalListeners(SignalListener[])

Method Detail

add

public static SignalListener add(SignalListener currentObject,
                                 SignalListener newObject)

Perform the add method and return the SignalListener result.

Parameters:

currentObject - SignalListener

newObject - SignalListener

Returns:

Results of the add (SignalListener) value.

remove

public static SignalListener remove(SignalListener currentObject,
                                    SignalListener removeObject)

Perform the remove method and return the SignalListener result.

Parameters:

currentObject - SignalListener

removeObject - SignalListener

Returns:

Results of the remove (SignalListener) value.

See Also:

remove(SignalListener)

errorOccurred

public void errorOccurred(java.lang.Object source,
                          java.lang.Object timestamp,
                          java.lang.Object data)

The errorOccurred method is called when an error has occurred. 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:

errorOccurred in interface ErrorListener

Parameters:

source - The source object that detected the error.

timestamp - The time at which the error was detected.

data - Contains any data about the error.

See Also:

signalOccurred(SignalService,Object,Object)

getObjects

public SignalListener[] getObjects()

Gets the SignalListener[] objects property value.

Returns:

Results of the get objects (SignalListener[]) value.

remove

protected SignalListener remove(SignalListener removeHandler)

Perform the remove method and return the SignalListener result.

Parameters:

removeHandler - SignalListener

Returns:

Results of the remove (SignalListener) value.

See Also:

remove(SignalListener,SignalListener)

signalOccurred

public void signalOccurred(SignalService source,
                           java.lang.Object timestamp,
                           java.lang.Object data)

This method is fired to all Listeners each time the signal triggerred. The signal can be triggered when a message is recevied from the hardware or when the trigger method is invoked by the application. 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:

signalOccurred in interface SignalListener

Parameters:

source - The SignalService which fired.

timestamp - The time at which the signal was detected.

data - Contains any data which was contained within the signal.

errorOccurred(Object,Object,Object)
