eventCounter

Class DataCounter

java.lang.Object

eventCounter.DataCounter

All Implemented Interfaces:

PamObserver

public class DataCounter
extends java.lang.Object
implements PamObserver

Class for counting events - e.g. clicks, whistles, etc.
Does not hold references to original dataunits but just holds a time reference for each event so that not too much memory is used. The click counter was causing problems since it would hold far too many clicks in memory.

Constructor Detail

DataCounter

public DataCounter(java.lang.String name,
           PamDataBlock sourceData,
           int countSeconds)

Method Detail

getDataCountSeconds

public int getDataCountSeconds()

setDataCountSeconds

public void setDataCountSeconds(int countSeconds)

getObserverName

public java.lang.String getObserverName()

Specified by:

getObserverName in interface PamObserver

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.

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

masterClockUpdate

public void masterClockUpdate(long milliSeconds,
                     long sampleNumber)

Specified by:

masterClockUpdate in interface PamObserver

noteNewSettings

public void noteNewSettings()

Specified by:

noteNewSettings in interface PamObserver

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.

update

public void update(PamObservable o,
          PamDataUnit arg)

Description copied from interface: PamObserver

Informs the PamObserver that new data have been added to the Observable class

Specified by:

update in interface PamObserver

Parameters:

o - Reference to the Observable (a PamDataBlock)

arg - Reference to the new PamDataUnit
