Constructor Detail

MeasurementListeners

public MeasurementListeners(MeasurementListener[] objects)

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

Parameters:

objects - MeasurementListener[]

See Also:

MeasurementListeners(MeasurementListener,MeasurementListener)

MeasurementListeners

public MeasurementListeners(MeasurementListener currentObject,
                            MeasurementListener newObject)

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

Parameters:

currentObject - MeasurementListener

newObject - MeasurementListener

See Also:

MeasurementListeners(MeasurementListener[])

Method Detail

add

public static MeasurementListener add(MeasurementListener currentObject,
                                      MeasurementListener newObject)

Perform the add method and return the MeasurementListener result.

Parameters:

currentObject - MeasurementListener

newObject - MeasurementListener

Returns:

Results of the add (MeasurementListener) value.

remove

public static MeasurementListener remove(MeasurementListener currentObject,
                                         MeasurementListener removeObject)

Perform the remove method and return the MeasurementListener result.

Parameters:

currentObject - MeasurementListener

removeObject - MeasurementListener

Returns:

Results of the remove (MeasurementListener) value.

See Also:

remove(MeasurementListener)

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.

getObjects

public MeasurementListener[] getObjects()

Gets the MeasurementListener [] objects property value.

Returns:

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

measurementChanged

public void measurementChanged(MeasurementService source,
                               java.lang.Object timestamp,
                               java.lang.Object newValue,
                               java.lang.Object oldValue)

This method is fired to all Listeners each time the value of the measurement changes. 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:

measurementChanged in interface MeasurementListener

Parameters:

source - MeasurementService which changed.

timestamp - The time at which the value change was detected.

newValue - The new value of the MeasurementService.

oldValue - The old value of the MeasurementService.

remove

protected MeasurementListener remove(MeasurementListener removeHandler)

Perform the remove method and return the MeasurementListener result.

Parameters:

removeHandler - MeasurementListener

Returns:

Results of the remove (MeasurementListener) value.

remove(MeasurementListener,MeasurementListener)
