public DollBrainFPNfilter(AEChip chip)

Method Detail

filterPacket

public EventPacket filterPacket(EventPacket in)

filters in to out. if filtering is enabled, the number of out may be less than the number put in

Specified by:

filterPacket in class EventFilter2D

Parameters:

in - input events can be null or empty.

Returns:

the processed events, may be fewer in number. filtering may occur in place in the in packet.

getRecordingFPN

public boolean getRecordingFPN()

setRecordingFPN

public void setRecordingFPN(boolean recordingFPN)

getFilterState

public java.lang.Object getFilterState()

Description copied from class: EventFilter

should return the filter state in some useful form

Specified by:

getFilterState in class EventFilter

resetFilter

public void resetFilter()

Description copied from class: EventFilter

should reset the filter to initial state

Specified by:

resetFilter in class EventFilter

update

public void update(java.util.Observable o,
                   java.lang.Object arg)

Specified by:

update in interface java.util.Observer

initFilter

public void initFilter()

Description copied from class: EventFilter

this should allocate and initialize memory: it may be called when the chip e.g. size parameters are changed after creation of the filter

Specified by:

initFilter in class EventFilter
