Method Detail

getObserverObject

public PamObserver getObserverObject()

Specified by:

getObserverObject in interface PamObserver

Returns:

the actual observer. In most cases concrete classes will just return 'this' in response. The exception is the Threaded observer, which will return the single thread observer.

getWestAxis

public PamAxis getWestAxis()

Overrides:

getWestAxis in class DisplayPanel

containerNotification

public void containerNotification(DisplayPanelContainer displayContainer,
                                  int noteType)

Description copied from class: DisplayPanel

Called by the DisplayPanelContainer whenever the scales change - e.g. every time new data is drawn on the spectrogram.

The display panel can use this information in two ways:

Firstly, it should clear the region of the display just ahead of the current spectrogram x coordinate. Secondly, it may draw additional data on the display.

Specified by:

containerNotification in class DisplayPanel

getYPixel

int getYPixel(double value)

destroyPanel

public void destroyPanel()

Description copied from class: DisplayPanel

The displayPanelContainer should call destroyPanel when the panel is no longer required so that the displayPanel can unsubscribe to any data it was observing.

Specified by:

destroyPanel in class DisplayPanel

getObserverName

public java.lang.String getObserverName()

Specified by:

getObserverName in interface PamObserver

getRequiredDataHistory

public long getRequiredDataHistory(PamObservable o,
                                   java.lang.Object arg)

Specified by:

getRequiredDataHistory in interface PamObserver

Parameters:

o - PamObservable class requiring the data

arg - optional argument from PamObservable

Returns:

time in milliseconds requried by data held in PamObservable

noteNewSettings

public void noteNewSettings()

Specified by:

noteNewSettings in interface PamObserver

removeObservable

public void removeObservable(PamObservable o)

Description copied from interface: PamObserver

called when an Observable (PamDataBlock) is removed from the system

Specified by:

removeObservable in interface PamObserver

setSampleRate

public void setSampleRate(float sampleRate,
                          boolean notify)

Description copied from interface: PamObserver

New sample rate

Specified by:

setSampleRate in interface PamObserver

notify - Notify other PamObservers and PamObservables in the chain.

masterClockUpdate

public void masterClockUpdate(long milliSeconds,
                              long sampleNumber)

Specified by:

masterClockUpdate in interface PamObserver

update

public void update(PamObservable o,
                   PamDataUnit arg)

new data have arrived - work out what channel it's from and plot it.

Specified by:

update in interface PamObserver

Parameters:

o - Reference to the Observable (a PamDataBlock)

arg - Reference to the new PamDataUnit
